windows2003下IIS6与TOMCAT6

一、下载所需要的文件

1、JRE 1.6下载地址(若要给服务器配置纯JSP运行环境则下载这个,若要做开发则下载第二个所述的JDK):
http://cds.sun.com/is-bin/INTERSHOP.enfinity/WFS/CDS-CDS_Developer-Site/en_US/-/USD/VerifyItem-Start/jre-6u10-beta-windows-i586-p.exe?BundledLineItemUUID=F19IBe.niuUAAAEaE_tKwKGt&OrderID=HkhIBe.nowcAAAEaAftKwKGt&ProductID=Yo9IBe.pkJkAAAEaTMMke24m&FileName=/jre-6u10-beta-windows-i586-p.exe

2、JDK 1.6下载地址(内含JRE1.6,要做java程序开发的程序员则下载这个):
http://cds.sun.com/is-bin/INTERSHOP.enfinity/WFS/CDS-CDS_Developer-Site/en_US/-/USD/VerifyItem-Start/jdk-6u10-beta-windows-i586-p.exe?BundledLineItemUUID=J81IBe.nOqoAAAEa6nVKwKGv&OrderID=Q1hIBe.n_ggAAAEa23VKwKGv&ProductID=0y1IBe.oylsAAAEac84Gcm4w&FileName=/jdk-6u10-beta-windows-i586-p.exe

3、Tomcat 6下载地址(java应用服务器软件,必须下载):
http://apache.mirror.phpchina.com/tomcat/tomcat-6/v6.0.16/bin/apache-tomcat-6.0.16.exe

4、JK-1.2.26下载地址(即下文所述的isapi_redirect.dll,是整合IIS 6与Tomcat 6的应用程序扩展接管文件):
http://apache.justdn.org/tomcat/tomcat-connectors/jk/binaries/win32/jk-1.2.26/isapi_redirect-1.2.26.dll

二、安装JDK/JRE和Tomcat

1、首先运行刚才下载的JRE1.6(只作服务器则安装这个)或JDK1.6(做java程序开发则安装这个)文件,安装过程很简单,根据向导选好安装路 径,一路点击下一步即可。这里假设JRE的安装路径是:C:\Program Files\Java\jre6;JDK的安装路径是:C:\Program Files\Java\jdk1.6.0_10

2、如果安装的是JRE1.6,可以跳过这一步,如果安装的是JDK1.6,则要添加如下环境变量的系统变量(具体设置地方位于“我的电脑-属性-高级-环境变量-系统变量”):
JAVA_HOME:C:\Program Files\Java\jdk1.6.0_10
classpath:.;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar;(.;一定不能少,因为它代表当前路径)
path:%JAVA_HOME%\bin (这个用分号隔开,补充在原来已有的字符串后面)

接着可以用记事本写一个简单的java程序来测试JDK是否已安装成功:
public class Test{
public static void main(String args[]){
System.out.println("This is a test program.");
}
}
将上面的这段程序保存为文件名为Test.java的文件(注意大小写要与程序的类名称一致)。
然后打开命令提示符窗口,cd到你的Test.java所在目录,然后键入下面的命令
javac Test.java
java Test
此时如果看到打印出来This is a test program.的话说明安装成功了,如果没有打印出这句话,你需要仔细检查一下你的配置情况。

3、接着运行刚才下载的Tomcat安装文件:apache-tomcat-6.0.16.exe,在安装过程中,会提示你选择JVM目录,一般情况下, 默认选择的路径都是对的,例如,如果你刚才安装的是JRE,路径是“C:\Program Files\Java\jre6”,如果安装的是JDK,路径则是“C:\Program Files\Java\jdk1.6.0_10\jre”,另外还有个安装部件的勾选,建议核心部分的三个选项都选上,特别是service部分,这个可 以让tomcat作为windows服务来运行。
     安装完Tomcat后,在我的电脑->属性->高级->环境变量->系统变量中添加以下环境变量(假定你的tomcat安装在 C:\Program Files\Apache Software Foundation\Tomcat 6.0):
CATALINA_HOME:C:\Program Files\Apache Software Foundation\Tomcat 6.0
CATALINA_BASE:C:\Program Files\Apache Software Foundation\Tomcat 6.0
TOMCAT_HOME:C:\Program Files\Apache Software Foundation\Tomcat 6.0

然后修改环境变量中的classpath,把tomat安装目录下的common\lib下的servlet.jar追加到classpath中去。
如果安装的是JDK,修改后的classpath如下:
classpath=.;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar;%CATALINA_HOME%\common\lib\servlet.jar;
如果安装的是JRE,修改后的classpath如下:
classpath=.;%CATALINA_HOME%\common\lib\servlet.jar;
接着可以启动tomcat,在IE中访问http://localhost:8080,如果看到tomcat的欢迎页面的话说明安装成功了。

三、检测直接用Tomcat平台运行JSP与Servlet程序是否成功

1、检测JSP

   A.到Tomcat的安装目录的webapps目录,可以看到ROOT,examples, tomcat-docs之类Tomcat自带的的目录;
   B.在webapps目录下新建一个目录,起名叫myapp;
   C.myapp下新建一个目录WEB-INF,注意,目录名称是区分大小写的;
   D.WEB-INF下新建一个文件web.xml,内容如下:

<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app>
<display-name>My Web Application</display-name>
<description>
A application for test.
</description>
</web-app>

   E.在myapp下新建一个测试的jsp页面,文件名为index.jsp,文件内容如下:

<html><body><center>
Now time is: <%=new java.util.Date()%>
</center></body></html>

   F.重启Tomcat(运行Tomcat后,在任务栏的托盘里有个带绿色向右方向小箭头的图标,那个就是Tomcat服务的图标,重启方法就是右键点击出菜单,先Stop服务,再start服务)
   G.打开浏览器,输入http://localhost:8080/myapp/index.jsp (注意网址大小写要与文件夹名以及文件名都一致)看到当前时间的话说明就成功了。

2、检测Servlet

   A.用记事本以HelloWorld.java文件名编辑你的第一个Servlet
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class HelloWorld extends HttpServlet
{
public void doGet(HttpServletRequest request,HttpServletResponse response)throws ServletException,IOException
{
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<html><head><title>");
out.println("This is my first Servlet");
out.println("</title></head><body>");
out.println("<h1>Hello,World!</h1>");
out.println("</body></html>");
}
}
   B.然后照样用javac HelloWorld.java来编译这个文件,如果出现编译错误,那么就是应该把Tomcat安装目录下的common\lib里面的 servlet.jar文件拷贝到JDK安装目录下的jre\lib\ext中,再次编译,就没有问题了!
   C.在你刚才建立的myapp文件夹中,进入WEB-INF文件夹内,再建一个classes文件夹,并将刚才编译生成的HelloWorld.class文件放进classes文件夹里。
   D.用记事本打开WEB-INF文件夹下的web.xml文件,修改成如下并保存:

<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app>
<display-name>My Web Application</display-name>
<description>
A application for test.
</description>
<servlet>
     <servlet-name>HelloWorld</servlet-name>
     <servlet-class>HelloWorld</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HelloWorld</servlet-name>
     <url-pattern>/HelloWorld</url-pattern>
</servlet-mapping>
</web-app>

   E.重启Tomcat服务
   F.在浏览器输入http://localhost:8080/servlet/HelloWorld ,如果页面出现大号字的Hello,World!,表示Servlet也运行成功了。

四、用JK整合IIS 6与Tomcat 6
1、首先在Tomcat安装目录的conf文件夹下,用记事本建立这两个文件:workers.properties与uriworkermap.properties
   workers.properties文件的内容是:

workers.tomcat_home=D:\Program Files\Apache Software Foundation\Tomcat 6.0\
workers.java_home=D:\Program Files\Java\jdk1.6.0_10\ (如果安装的是JRE则去掉这行)
ps=\
worker.list=ajp13
worker.ajp13.port=8009
worker.ajp13.host=localhost
worker.ajp13.type=ajp13
worker.ajp13.lbfactor=1

   uriworkermap.properties文件的内容是:

/*.jsp=ajp13
/*.do=ajp13
!/*.jpg=ajp13
!/*.gif=ajp13
!/*.bmp=ajp13

2、用记事本建立一个扩展名为reg的注册表导入文件,文件名随意,我命名的是isapi_redirect.reg,假设Tomcat安装目录是 “C:\Program Files\Apache Software Foundation\Tomcat 6.0”,JK文件名为“isapi_redirect.dll”,则reg文件内容如下(Tomcat安装目录与JK文件名不同的请对应修改内容):

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Apache Software Foundation\Jakarta Isapi Redirector\1.0]
"log_file"="C:\\Program Files\\Apache Software Foundation\\Tomcat 6.0\\logs\\isapi.log"
"log_level"="debug"
"worker_file"="C:\\Program Files\\Apache Software Foundation\\Tomcat 6.0\\conf\\workers.properties"
"worker_mount_file"="C:\\Program Files\\Apache Software Foundation\\Tomcat 6.0\\conf\\uriworkermap.properties"
"extension_uri"="/jakarta/isapi_redirect.dll"

然后双击运行isapi_redirect.reg文件,将注册资料导入注册表,显示导入成功后,再打开注册表检查 HKEY_LOCAL_MACHINE\SOFTWARE\Apache Software Foundation\Jakarta Isapi Redirector\1.0中对应的项目与其值是否都有都对了:

extension_uri /jakarta/isapi_redirect.dll (jakarta为IIS下的虚拟目录)
log_file C:\Program Files\Apache Software Foundation\Tomcat 6.0\logs\isapi.log (指定JK插件使用的日志文件)
log_level debug (指定日志记录类型)
worker_file C:\Program Files\Apache Software Foundation\Tomcat 6.0\conf\workers.properties (指定JK插件的工作文件)
worker_mount_file C:\Program Files\Apache Software Foundation\Tomcat 6.0\conf\uriworkermap.properties (指定JK插件的URL映射)

如果没有上述项,则建立相关项和相关值。

3、配置IIS
   A.在“Internet信息服务管理器”的“网站”中的“Web服务扩展”上点右键选择“添加一个新的Web服务扩展”,弹出的框中扩展名填JSP(无 所谓的,自己随便设置名称),“要求的文件”选“添加”然后找到你的isapi_redirector.dll后“确定”,“设置扩展状态为允许”也打上 勾,确定。
   B.在“Internet信息服务管理器”的“默认网站”点右键选“属性”,在弹出的页框里选择“ISAPI筛选器”,点“添加”,筛选器名称填jakarta,可执行文件中填入你的isapi_redirector.dll的绝对路径,然后点“确定”。
   C.同样是在默认站点的属性窗口里,切换到“主目录”界面,将目录路径改为上面“检测JSP”步骤建立的myapp文件夹路径,点击“应用程序设置”区域 的“配置”按钮,打开配置窗口,在应用程序扩展点击添加,可执行文件浏览找到你的isapi_redirector.dll文件,并将文件路径前后用英文 双引号括起来,扩展名填“.jsp”,动作限制为“GET,HEAD,POST,DEBUG”(添加这个应用程序扩展的作用是为了实现在默认文档里添加 jsp文件名时,IIS能自动识别,否则,即使在默认文档里添加了index.jsp之类的名称,网址不写具体文件名的话,就不能默认执行指定的jsp文 件),然后一路点击确定,关闭属性页。
   D.再在“默认网站”上点右键,选择“新建”->“虚拟目录”,别名填jakarta,下一步,路径选为你的 isapi_redirector.dll存放的目录,下一步,权限中记得把“执行”那项打勾,完成后,再右键点击这个刚建好的虚拟目录,选“属性”,在 属性窗口的“虚拟目录”界面上,将“执行权限”改为“脚本和可执行文件”,然后应用确定。
   E.用记事本打开Tomcant安装目录conf文件夹下的server.xml文件,假设你的myapp路径是“C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\myapp”,在server.xml文件的</Host>标签前面加上一行:
<Context path="" reloadable="true" docBase="C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\myapp" workDir="C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\myapp\work" />

这行的作用是更改Tomcat的默认站点主目录
   F.重启Tomcat服务。
   至此,IIS 6与Tomcat 6的整合就完成了,下面访问http://localhost/index.jsp看看,显示的结果与http://localhost:8080/index.jsp是否一致?如果一致的话,恭喜你,你成功了!如果你还在默认站点属性窗口的默认站点里添加了index.jsp,那么你直接访问http://localhost,一样能显示同样的结果!

五、快速添加第二个JSP虚拟站点
   1、在“Internet信息服务管理器”新建一个虚拟站点,主机头添加上你的域名,假设有两个域名:“jsp.testdomain.com" 与“test.testdomain.com”。
   2、在这个新建的虚拟站点上,重复“四”的B、C、D步骤,所不同的是填写的主目录路径不同,这里的路径可以填写你真正JSP站点文件夹所在的目录,这个文件夹可以放在任何一个盘的任何一个目录,这里假设是“C:\WebSite\MyJSP”。
   3、用记事本打开Tomcat安装目录下的Server.xml,在</Engine>标签前面加上下面的内容(每在IIS增加一个JSP虚拟站点,都要对应地在Server.xml加上下面的内容)后保存:

<Host name="jsp.KapokNet.com"   appBase="C:\WebSite\MyJSP"
             unpackWARs="true" autoDeploy="true"
             xmlValidation="false" xmlNamespaceAware="false">
   <Alias>test.kapoknet.com</Alias>
   <Context path="" reloadable="true" docBase="C:\WebSite\MyJSP" workDir="C:\WebSite\MyJSP\work" />
</Host>

   4、重启Tomcat。
   至此,一个新的JSP虚拟站点就完成部署了,只要所绑定的域名解析到了所在的服务器,直接用该域名就能访问执行JSP文件,不需要通过8080端口了。
   至于Servlet的执行,在IIS下面,目前需要通过将定义Servlet的xml文件里对应的Servlet程序名url定义加上.jsp,映射为 JSP文件名,才能正确直接访问执行,运行效果是与Servlet一样的,用上面所建的Servlet为例,假设Servlet名称为 HelloWorld,具体实现方法就是将WEB-INF文件夹下的web.xml文件的“<url- pattern>/HelloWorld</url-pattern>”修改为“<url-pattern> /HelloWorld.jsp</url-pattern>”,整个web.xml修改后的内容如下:

<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app>
<display-name>My Web Application</display-name>
<description>
A application for test.
</description>
<servlet>
     <servlet-name>HelloWorld</servlet-name>
     <servlet-class>HelloWorld</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HelloWorld</servlet-name>
     <url-pattern>/HelloWorld.jsp</url-pattern>
</servlet-mapping>
</web-app>

六、实际效果演示
   1、默认jsp网页访问:http://jsp.testdomain.com 或 http://test.testdomain.com
   2、jsp网页直接访问:http://jsp.testdomaincom/index.jsp
   3、映射为jsp文件的Servlet程序的演示访问:http://jsp.testdomain.com/HelloWorld.jsp

   1、2就是上面写的显示系统时间的一个最简单JSP程序,3就是输出显示大号字的HelloWorld!。

6.鼠标移到GridView某一行时改变该行的背景色方法一:

效果图:

做法:
双击GridView的OnRowDataBound事件;
在后台的GridView1_RowDataBound()方法添加代码,最后代码如下所示:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        int i;
        //执行循环,保证每条数据都可以更新
        for (i = 0; i < GridView1.Rows.Count; i++)
        {
            //首先判断是否是数据行
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                //当鼠标停留时更改背景色
                e.Row.Attributes.Add("onmouseover", "c=this.style.backgroundColor;this.style.backgroundColor='#00A9FF'");
                //当鼠标移开时还原背景色
                e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=c");
            }
        }

    }

前台代码:

    </div>
    </form>

</html>

7.鼠标移到GridView某一行时改变该行的背景色方法二:

效果图:

做法:和上面的一样就是代码不同
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        //int i;
        ////执行循环,保证每条数据都可以更新
        //for (i = 0; i < GridView1.Rows.Count; i++)
        //{
        //    //首先判断是否是数据行
        //    if (e.Row.RowType == DataControlRowType.DataRow)
        //    {
        //        //当鼠标停留时更改背景色
        //        e.Row.Attributes.Add("onmouseover", "c=this.style.backgroundColor;this.style.backgroundColor='#00A9FF'");
        //        //当鼠标移开时还原背景色
        //        e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=c");
        //    }
        //}
        //如果是绑定数据行
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            //鼠标经过时,行背景色变
            e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#E6F5FA'");
            //鼠标移出时,行背景色变
            e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#FFFFFF'");
        }

    }

8.GridView实现删除时弹出确认对话框:

效果图:

实现方法:
双击GridView的OnRowDataBound事件;
在后台的GridView1_RowDataBound()方法添加代码,最后代码如下所示:

    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        //如果是绑定数据行
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
             if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)
            {
                ((LinkButton)e.Row.Cells[6].Controls[0]).Attributes.Add("onclick", "javascript:return confirm('你确认要删除:\"" + e.Row.Cells[1].Text + "\"吗?')");
            }
        }

    }
 

9.GridView实现自动编号:

效果图:

实现方法:
双击GridView的OnRowDataBound事件;
在后台的GridView1_RowDataBound()方法添加代码,最后代码如下所示:
    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        //如果是绑定数据行 //清清月儿http://blog.csdn.net/21aspnet 
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            ////鼠标经过时,行背景色变
            //e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#E6F5FA'");
            ////鼠标移出时,行背景色变
            //e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#FFFFFF'");

            ////当有编辑列时,避免出错,要加的RowState判断
            //if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)
            //{
            //    ((LinkButton)e.Row.Cells[6].Controls[0]).Attributes.Add("onclick", "javascript:return confirm('你确认要删除:\"" + e.Row.Cells[1].Text + "\"吗?')");
            //}

        }
        if (e.Row.RowIndex != -1)
        {
            int id = e.Row.RowIndex + 1;
            e.Row.Cells[0].Text = id.ToString();
        }

    }

 

注意这时最好把前台的第一列的表头该为“编号”,因为以前的第一列被“吃掉”了。
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="3" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing"
                        OnRowUpdating="GridView1_RowUpdating" OnRowCancelingEdit="GridView1_RowCancelingEdit" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" Font-Size="12px" OnRowDataBound="GridView1_RowDataBound">
                        <FooterStyle BackColor="White" ForeColor="#000066" />
                        <Columns>
                            <asp:BoundField DataField="身份证号码" HeaderText="编号" ReadOnly="True" />
                            <asp:BoundField DataField="姓名" HeaderText="用户姓名" />
                            <asp:BoundField DataField="员工性别" HeaderText="性别" />
                            <asp:BoundField DataField="家庭住址" HeaderText="家庭住址" />
                            <asp:CommandField HeaderText="选择" ShowSelectButton="True" />
                            <asp:CommandField HeaderText="编辑" ShowEditButton="True" />
                            <asp:CommandField HeaderText="删除" ShowDeleteButton="True" />
                        </Columns>
                        <RowStyle ForeColor="#000066" />
                        <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />
                        <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />
                        <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />
                    </asp:GridView>

10.GridView实现自定义时间货币等字符串格式:

效果图:
图1-未格式化前

图2-格式化后

解决方法:

在asp.net 2.0中,如果要在绑定列中显示比如日期格式等,如果用下面的方法是显示不了的

<asp :BoundField DataField="CreationDate"
DataFormatString="{0:M-dd-yyyy}"
HeaderText="CreationDate" />

主要是由于htmlencode属性默认设置为true,已防止XSS攻击,安全起见而用的,所以,可以有以下两种方法解决

1、

<asp :GridView ID="GridView1" runat="server">
<columns>
<asp :BoundField DataField="CreationDate"
DataFormatString="{0:M-dd-yyyy}"
HtmlEncode="false"
HeaderText="CreationDate" />
</columns>
</asp>

将htmlencode设置为false即可

另外的解决方法为,使用模版列

<asp :GridView ID="GridView3" runat="server" >
<columns>
<asp :TemplateField HeaderText="CreationDate" >
<edititemtemplate>
<asp :Label ID="Label1" runat="server"
Text='<%# Eval("CreationDate", "{0:M-dd-yyyy}") %>'>
</asp>
</edititemtemplate>
<itemtemplate>
<asp :Label ID="Label1" runat="server"
Text=’<%# Bind("CreationDate", "{0:M-dd-yyyy}") %>'>
</asp>
</itemtemplate>
</asp>
</columns>
</asp>

前台代码:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="身份证号码"
            DataSourceID="SqlDataSource1" AllowSorting="True" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" CellPadding="3" Font-Size="12px" OnRowDataBound="GridView1_RowDataBound">
            <Columns>
                <asp:BoundField DataField="身份证号码" HeaderText="身份证号码" ReadOnly="True" SortExpression="身份证号码" />
                <asp:BoundField DataField="姓名" HeaderText="姓名" SortExpression="姓名" />
                <asp:BoundField DataField="邮政编码" HeaderText="邮政编码" SortExpression="邮政编码" />
                <asp:BoundField DataField="出生日期" HeaderText="出生日期" SortExpression="出生日期" />
                <asp:BoundField DataField="起薪" HeaderText="起薪" SortExpression="起薪" />
            </Columns>
            <FooterStyle BackColor="White" ForeColor="#000066" />
            <RowStyle ForeColor="#000066" />
            <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />
            <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />
            <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />
        </asp:GridView>
        <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:北风贸易ConnectionString1 %>"
            SelectCommand="Select top 5 [出生日期], [起薪], [身份证号码], [姓名], [家庭住址], [邮政编码] FROM [飞狐工作室]" DataSourceMode="DataReader"></asp:SqlDataSource>

附录-常用格式化公式:
{0:C}  货币;
{0:D4}由0填充的4个字符宽的字段中显示整数;
{0:000.0}四舍五入小数点保留第几位有效数字;
{0:N2}小数点保留2位有效数字;{0:N2}%   小数点保留2位有效数字加百分号;
{0:D}长日期;{0:d}短日期;{0:yy-MM-dd}   例如07-3-25;;{0:yyyy-MM-dd}  例如2007-3-25
 

 11.GridView实现用“…”代替超长字符串:

效果图:

解决方法:数据绑定后过滤每一行即可
for (int i = 0; i <= GridView1.Rows.Count – 1; i++)
        {
            DataRowView mydrv;
            string gIntro;
            if (GridView1.PageIndex == 0)
            {
                mydrv = myds.Tables["飞狐工作室"].DefaultView[i];//表名
                gIntro = Convert.ToString(mydrv["家庭住址"]);//所要处理的字段
                GridView1.Rows[i].Cells[3].Text = SubStr(gIntro, 2);
            }
            else
            {
                mydrv = myds.Tables["飞狐工作室"].DefaultView[i + (5 * GridView1.PageIndex)];
                gIntro = Convert.ToString(mydrv["家庭住址"]);
                GridView1.Rows[i].Cells[3].Text = SubStr(gIntro, 2);
            }
        } 

调用的方法:

    public string SubStr(string sString, int nLeng)
    {
        if (sString.Length <= nLeng)
        {
            return sString;
        }

        sNewStr = sNewStr + "…";
        return sNewStr;

    }
}

 11.GridView一般换行与强制换行:

效果图:

首先设置<asp:BoundField DataField="家庭住址" HeaderText="家庭住址"  ItemStyle-Width="100" />
gridview里有一列绑定的数据很长,显示的时候在一行里面显示,页面拉得很宽。
原因是连续英文段为一个整体导致的,在RowDataBound中添加上了一句e.Row.Cells[2].Style.Add("word-break", "break-all")就可以。

如果要给所有的列增加此属性:
 protected void Page_Load(object sender, EventArgs e)
    {
        //正常换行
        GridView1.Attributes.Add("style", "word-break:keep-all;word-wrap:normal");
        //下面这行是自动换行
        GridView1.Attributes.Add("style", "word-break:break-all;word-wrap:break-word");
        if (!IsPostBack)
        {
             bind();//调用数据绑定即可
        }
    }
总之:善用CSS的word-break:break-all;word-wrap:break-word属性即可,这个属性是通用的对于顽固的南换行问题都可以解决,不局限于GridView。

 12.GridView显示隐藏某一列:
本方案为月儿独创,不同于网上其他方式,我觉得用一个CheckBox更人性化,这样可以隐藏不必要的列,让用户自己选择需要出现的列,在处理多列时这是一个很好的解决方案!

效果图:
图1-开始

图2-点击显示的CheckBox后

解决方案:
public void bind()
    {
        string sqlstr = "select top 5 * from 飞狐工作室";
        sqlcon = new SqlConnection(strCon);
        SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon);
        DataSet myds = new DataSet();
        sqlcon.Open();
        myda.Fill(myds, "飞狐工作室");
        GridView1.DataSource = myds;
        GridView1.DataKeyNames = new string[] { "身份证号码" };
        GridView1.DataBind();
        sqlcon.Close();
        GridView1.Columns[3].Visible = false;//一开始隐藏
        CheckBox1.Checked = false;//如果不这样后面的代码会把他True

    }

双击CheckBox1,在CheckedChanged方法里写上代码,最后代码如下:
protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
    {
         GridView1.Columns[3].Visible=! GridView1.Columns[3].Visible;
         Response.Write("GridView1的第4列现在的显示隐藏状态是:"+GridView1.Columns[3].Visible.ToString());
    }

注意:CheckBox1的AutoPostBack要True

 13.GridView弹出新页面/弹出制定大小位置新窗口:

效果图:

方案一:简单的方法,新窗口不固定大小
 <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="3" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing"
                        OnRowUpdating="GridView1_RowUpdating" OnRowCancelingEdit="GridView1_RowCancelingEdit" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" Font-Size="12px"  >
                        <FooterStyle BackColor="White" ForeColor="#000066" />
                        <Columns>
                            <asp:BoundField DataField="身份证号码" HeaderText="编号" ReadOnly="True" />
                            <asp:BoundField DataField="邮政编码" HeaderText="邮政编码" SortExpression="邮政编码" />
                            <asp:BoundField DataField="家庭住址" HeaderText="家庭住址"  />
                            <asp:HyperLinkField HeaderText="姓名" Text="姓名" DataNavigateUrlFields=" 姓名" DataNavigateUrlFormatString="Default6.aspx?GoodsID={0}" Target="mainframe" NavigateUrl="~/Default6.aspx" DataTextField="姓名" >
                    </asp:HyperLinkField>
                            <asp:CommandField HeaderText="选择" ShowSelectButton="True" />
                            <asp:CommandField HeaderText="编辑" ShowEditButton="True" />
                            <asp:CommandField HeaderText="删除" ShowDeleteButton="True" />
                        </Columns>
                        <RowStyle ForeColor="#000066" />
                        <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />
                        <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />
                        <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />
                    </asp:GridView>
DataNavigateUrlFields是链接的字段名,DataNavigateUrlFormatString是路径。

方案二:精确控制弹出窗口大小位置
<asp:HyperLinkColumn DataNavigateUrlField="EmployeeID" DataNavigateUrlFormatString="javascript:varwin=window.open('detail.aspx?ID={0}',null,'width=300,height=200');window.Close();"
       DataTextField="LastName" HeaderText="LastName"></asp:HyperLinkColumn>

使用的是结合javascript的window.open方法,关于window.open的参数网上有很多帖子,本站也有许多参考
弹出窗口大全 http://blog.csdn.net/21aspnet/archive/2004/10/25/150231.aspx   即可!

  14.GridView固定表头(不用javascript只用CSS!,很好用)

效果图:

代码:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>GridView固定表头 清清月儿http://blog.csdn.net/21aspnet </title>
        <style>
.Freezing
   {
   
   position:relative ;
   table-layout:fixed;
   top:expression(this.offsetParent.scrollTop);  
   z-index: 10;
   }

.Freezing th{text-overflow:ellipsis;overflow:hidden;white-space: nowrap;padding:2px;}
</style>
</head>
<body style="font-size=12px">
    <form id="form1" runat="server">
    <div style="overflow-y: scroll; height: 200px;width:300px" id="dvBody">
                   <asp:GridView ID="GridView1" runat="server"    AutoGenerateColumns="False" CellPadding="3" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing"
                        OnRowUpdating="GridView1_RowUpdating" OnRowCancelingEdit="GridView1_RowCancelingEdit" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" Font-Size="12px" OnRowCreated="GridView1_RowCreated"  >
                        <FooterStyle BackColor="White" ForeColor="#000066" />
                        <Columns>
                            <asp:BoundField DataField="身份证号码" HeaderText="编号" ReadOnly="True" />
                            <asp:BoundField DataField="邮政编码" HeaderText="邮政编码" SortExpression="邮政编码" />
                            <asp:BoundField DataField="家庭住址" HeaderText="家庭住址"  />
                            <asp:BoundField DataField="姓名" HeaderText="姓名"  />
                           
                        </Columns>
                        <RowStyle ForeColor="#000066" />
                        <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />
                        <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left"  CssClass="ms-formlabel DataGridFixedHeader"/>
                        <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" CssClass="Freezing"/>
                    </asp:GridView>
        </div>

    </form>
</body>
</html>

用法:CSS设如上的样式,HeaderStyle加CssClass="Freezing,套住GridView的Div设置高度宽度 <div style="overflow-y: scroll; height: 200px;width:200px" >

 17.GridView加入自动求和求平均值小计

效果图:
解决方案:    
private double sum = 0;//取指定列的数据和,你要根据具体情况对待可能你要处理的是int
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
       
        if (e.Row.RowIndex >= 0)
        {
            sum += Convert.ToDouble(e.Row.Cells[6].Text);
        }
        else if (e.Row.RowType == DataControlRowType.Footer)
        {
            e.Row.Cells[5].Text = "总薪水为:";
            e.Row.Cells[6].Text = sum.ToString();
            e.Row.Cells[3].Text = "平均薪水为:";
            e.Row.Cells[4].Text = ((int)(sum / GridView1.Rows.Count)).ToString();
           
        }
    }

前台:唯一的花头就是设置ShowFooter="True" ,否则默认表头为隐藏的!

 18.GridView数据导入Excel/Excel数据读入GridView

效果图:

解决方案:
页面增加一个按钮,单击事件添加如下方法:
protected void Button1_Click(object sender, EventArgs e)
    {
        Export("application/ms-excel", "学生成绩报表.xls");
    }

    private void Export(string FileType, string FileName)
    {
        Response.Charset = "GB2312";
        Response.ContentEncoding = System.Text.Encoding.UTF7;
        Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(FileName, Encoding.UTF8).ToString());
        Response.ContentType = FileType;
        this.EnableViewState = false;
        StringWriter tw = new StringWriter();
        HtmlTextWriter hw = new HtmlTextWriter(tw);
        GridView1.RenderControl(hw);
        Response.Write(tw.ToString());
        Response.End();
    }
//如果没有下面方法会报错类型“GridView”的控件“GridView1”必须放在具有 runat=server 的窗体标记内
   
public override void VerifyRenderingInServerForm(Control control)
    {
    }
还有由于是文件操作所以要引入名称空间IO和Text

    }
   
    public void bind()
    {
        string sqlstr = "select top 5 * from 飞狐工作室";
        sqlcon = new SqlConnection(strCon);
        SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon);
        DataSet myds = new DataSet();
        sqlcon.Open();
        myda.Fill(myds, "飞狐工作室");
        GridView1.DataSource = myds;
        GridView1.DataKeyNames = new string[] { "身份证号码" };
        GridView1.DataBind();
        sqlcon.Close();
    }

    protected void Button1_Click(object sender, EventArgs e)

        HtmlTextWriter hw = new HtmlTextWriter(tw);
        GridView1.RenderControl(hw);
