我说的够清楚了
首先添加按钮，然后按钮的commandname 你得赋值方便后面处理按钮的单击事件
然后在repeater事件里面写按钮的单击事件代码
<ItemTemplate>
<TABLE id="Table3" style="WIDTH: 197px; HEIGHT: 27px" cellSpacing="1" cellPadding="1" width="197"
align="center" border="0">
<TR>
<TD>
<asp:LinkButton id=btnSelect runat="server" ForeColor="MidnightBlue" CommandName="edit">
</asp:LinkButton></TD>
</TR>
</TABLE>
</ItemTemplate>

因为我用的是datalist而且button的commandname是edit所以是在datalist的editcommand事件里面写单击按钮的事件代码！！！！！
不过repeater是一样的
private void DataList1_EditCommand(object source, System.Web.UI.WebControls.DataListCommandEventArgs e)
{
//链接查询
LinkButton select =(LinkButton)e.Item.FindControl("btnSelect");
string DeptType = select.ToolTip.Trim();
int Index = DeptType.IndexOf("_");
string DeptTypeId = DeptType.Substring(0,Index);
Response.Redirect("DeptPhoneQuery.aspx?id="+DeptTypeId);
//Redirect
}

指定里面的repeater的ItemCommand事件
such as:

Repeater in_repeater=OuterRepeater.Controls.Find("InsideRepeater");

in_repeater.ItemCommand += new .....
button（linkbutton,imagebutton）控件类型的事件已经上传到父控件了，ItemCommand 可以接收到上传的事件。其他类型的控件可调用raisebubbleevent来上传事件。
