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。
