GridView点击更新按钮两次才会触发

Question

我的GridView中一列命令列,编辑更新,点击编辑按钮后,会正常转为编辑状态,但是再点击更新按钮时,第一次点击,此行中所有输入框中的内容会清空,而且不会触发RowUpdating事件,第二次点击时才会触发RowUpdating事件.GridView中有两列是模板列,数据绑定也能正常显示.请问这种情况是什么原因呢

Answer 2

第一次点击更新按钮仅会触发PageLoad事件,第二次点击会触发PageLoad事件和RowUpdating事件

Answer 3

刚在vs2010中试了一下没有问题确认父控件的ID 是否明确

Answer 4

父控件?GridView没有父控件了<body>
    <form id="form1" runat="server">
    <div> 
        <asp:GridView ID="GridView1" runat="server"  AutoGenerateColumns="False" 
            CellPadding="4" ForeColor="#333333" ShowFooter="True" DataKeyNames="ID" 
            onrowcancelingedit="GridView1_RowCancelingEdit" 
            onrowdeleting="GridView1_RowDeleting" onrowediting="GridView1_RowEditing" 
            onrowupdating="GridView1_RowUpdating">
