Repeater 中 OnItemCommand 用法

 <table>
     <asp:Repeater ID="rptList" runat="server"OnItemCommand="rptList_ItemCommand">
     <ItemTemplate>
 <tr>
     <td><asp:TextBox ID="txtNum" runat="server" Text='<%#Eval("ProNum")%>'></asp:TextBox></td>
     <td><asp:Button ID="btnUpdate" runat="server" Text="更新"CommandName="update" CommandArgument='<%#Eval("PID") %>' /></td>
 </tr>
     </ItemTemplate>
     </asp:Repeater>
 </table>

 protected void rptList_ItemCommand(object source, RepeaterCommandEventArgs e)
 {
     switch (e.CommandName)
      {
         case "update":
             string arg = e.CommandArgument.ToString();//取得参数
             //找到激发事件的行内控件，这个很有用，能将更多需要的参数值传递过来。
              TextBox txtNum = e.Item.FindControl("txtNum") as TextBox;

             //下面执行业务逻辑
             string jsStr = "<script>alert('删除成功!" + txtNum.Text + "')</script>";
              Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "alert", jsStr,false);
             break;
      }

 }

控件还是比较好理解~~
