Gridview下点ImageButton没有反应？

Question

<asp:GridView ID="dvPostBack" runat="server" onrowcommand="dvPostBack_RowCommand" >
 <Columns>
    <asp:TemplateField Visible="false">
                       <ItemTemplate>
                          <asp:Label ID="lbl_PostbackId" Visible="false" runat="server" Text='<%#Eval("PostBack_Id") %>'></asp:Label>
                        </ItemTemplate>
                       </asp:TemplateField>   <asp:TemplateField>
      <ItemTemplate>
         .......
<asp:ImageButton ID="image1" runat="server" ImageUrl="~/images/quote.gif"  CommandName="Post_Back"  /> 
</asp:GridView> protected void dvPostBack_RowCommand(object sender, GridViewCommandEventArgs e)
        {
            if (e.CommandName == "Post_Back")//加断点，程序没有经过这里
            {
                foreach (GridViewRow gvr in this.dvPostBack.Rows)
                {
                    Label backid = (Label)gvr.FindControl("lbl_PostbackId");
                    ......
            }
同样我换成OnClick事件也是一样？请问代码是哪有问题？麻烦大家帮忙看看

Answer 1

foreach (GridViewRow gvr in this.dvPostBack.Rows)
                {
                    Label backid = (Label)gvr.FindControl("lbl_PostbackId");
你点击一次按钮就要遍历整个gridView?改下：选择当前行去寻找控件

Answer 2

ImageButton位置放的有点问题！

Answer 3

你不用imageButton,直接用botton 样式用图片就行了..

Answer 4

你这个imagebutton放在那个模板里面了...请仔细检查.

Answer 5

其实很简单，CausesValidation="false"加上后就可以了，谢谢大家了
