，后端代码如下：在我的代码中有任何问题请帮助谢谢

  protected void Img_btn_Click(object sender, ImageClickEventArgs e)
{
    ImageButton Bt = sender as ImageButton;
    GridViewRow GVRow = (GridViewRow)Bt.NamingContainer;
    ID_lbl.Text = User_grd.DataKeys[GVRow.RowIndex].Value.ToString();
    VoterName_txt.Text = GVRow.Cells[2].Text;
    State_txt.Text = GVRow.Cells[3].Text;
    District_txt.Text = GVRow.Cells[4].Text;
}

但是当我运行它时，事件没有被解雇..问题是什么？

 Your issue is somehow same....that i encountered few months back... look at this one ...this might help you some way or another... try using LINKBUTTON instead of BUTTON...

<asp:gridview runat="server" id="GridView1" showfooter="true" 
    autogeneratecolumns="false" GridLines="None" CssClass="table1"  

    OnRowCreated="GridView1_RowCreated" BorderColor="#356600" 
    BorderStyle="Solid" >
    <columns>
 <asp:TemplateField HeaderText="Date" >
<ItemTemplate>

<asp:LinkButton ID="Date" runat="server" CausesValidation="false"   CommandName="Date_Select"  Text='<%#Eval("Date","{0:yyyy-MM-dd}") %>' onclick="Date_Click" EnableTheming="False"></asp:LinkButton>

</ItemTemplate>
<EditItemTemplate>
</EditItemTemplate>
</asp:TemplateField>

<asp:boundfield datafield="Profit" headertext="Profit"
            footerstyle-font-bold="true">
<FooterStyle Font-Bold="True"></FooterStyle>
        </asp:boundfield>

   </columns>

protected void Date_Click(object sender, EventArgs e)
{

         LinkButton Lnk = (LinkButton)sender;

        Label1.Text = Lnk.Text; // This one works for me....

          OdbcConnection con1 = new OdbcConnection(ConfigurationManager.ConnectionStrings["connect1"].ConnectionString);
          OdbcCommand cmd = new OdbcCommand("select a.customer As Customer,a.mins as MIns,a.amount as Amount,a.profit as Profit from summarydatashort a,clientsrecord b where a.orig_clli=b.orig_clli and a.date='" + Label1.Text + "' and b.emplye='Ankit'", con1);
        con1.Open();
        OdbcDataAdapter da = new OdbcDataAdapter(cmd);
        da.Fill(ds);

        con1.Close();
        GridView17.DataSource = ds;
        GridView17.DataBind();


     }

图像按钮OnClick事件未触发
