虽然Repeater控件没有象GridView那样常用，但有一些特定的场合还是需要用到Repeater的，其实在Net2.0中，FormView控件也可以实现类似于Repeater的效果，而且都是通过模板（Template）来显示数据。
然而，在Repeater控件对控件进行删除就没有GridView那样简单。下面示例如下：
Default.aspx:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="Repeater_Default" %>
<!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>无标题页</title></head><body> <form id="form1" runat="server"> <div> <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>" SelectCommand="SELECT * FROM [Region]"></asp:SqlDataSource> </div> <asp:Repeater ID="Repeater1" runat="server" DataSourceID="SqlDataSource1" OnItemCommand="Repeater1_ItemCommand" OnItemCreated="Repeater1_ItemCreated"> <ItemTemplate > <table border="1"> <tr> <td> <asp:Label Text ='<%#Eval("regionid") %>' runat ="server" ID="Label1"></asp:Label> <asp:Label Text='<%#Eval("regiondescription") %>' runat="server" ></asp:Label> <asp:Button Text ="Delete" runat ="server" ID="Button1"/> </td> </tr> </table> </ItemTemplate> </asp:Repeater> </form></body></html>
Default.aspx.cs:
using System;using System.Data;using System.Configuration;using System.Collections;using System.Web;using System.Web.Security;using System.Web.UI;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using System.Web.UI.HtmlControls;using System.Data.SqlClient;
public partial class Repeater_Default : System.Web.UI.Page{ protected void Page_Load(object sender, EventArgs e) {
} protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e) { switch (((Button)e.Item.FindControl ("Button1")).Text) { case "Delete":
SqlConnection conn = new SqlConnection("server=.;database=northwind;uid=sa;pwd=sa;"); conn.Open(); SqlCommand comm = new SqlCommand("delete from region where regionid='" + ((Label)e.Item.FindControl("Label1")).Text+"'",conn ); comm.ExecuteNonQuery(); conn.Close();
Response.Write(((Label)e.Item.FindControl ("Label1")).Text); break; } } protected void Repeater1_ItemCreated(object sender, RepeaterItemEventArgs e) { for (int i = 0; i < this.Repeater1.Items.Count; i++) { ((Button)this.Repeater1.Items[i].FindControl("Button1")).Attributes.Add("onclick", "alert('ff')"); } }}
这样就可以实现删除了。
