GridView RowCommand Not Firing at all for image button

Question

Iam trying to fire rowCommand event on Image button click in my GridView. The GridView is inside Update Panel. But after trying all the means like:

EnableViewState,
Binding Grid on IsPostback,

Iam not able to get the exact reason.

Please find the code below:

 <asp:GridView ID="grdReport" runat="Server" CellPadding="0" Height="50%" HeaderStyle-CssClass="dataHeadStyle"
               OnPageIndexChanging="grdReport_PageIndexChanging" CssClass="lblStyle" AutoGenerateColumns="false" ShowHeader="true" ShowFooter="false"
               GridLines="Both" Width="100%" AlternatingRowStyle-CssClass="dataAltRowStyle"
               RowStyle-CssClass="dataItemsStyle2" DataKeyNames="TRAINING_ID" AllowPaging="true"
               PageSize="7" OnRowCommand="grdReport_RowCommand" OnRowDataBound="grdReport_RowDataBound" EnableViewState="true">

      <Columns>
            <asp:TemplateField HeaderText="Select" ItemStyle-CssClass="dataItemsStyle1">
                <ItemStyle HorizontalAlign="Center" Width="7%" />
                <HeaderStyle HorizontalAlign="Center" />
                <ItemTemplate>
                      <asp:ImageButton ID="ImgSelect" runat="server" CausesValidation="false" ImageUrl="~/Images/edit_icon.gif"
                                  CommandName="select" CommandArgument='<%# Eval("TRAINING_NAME")+","+ Eval("TRAINING_DESCRIPTION")+","+ Eval("TRAINING_DUE_DATE")%> '/>
                </ItemTemplate>
                <ControlStyle CssClass="ViewHand" />
           </asp:TemplateField>



protected void grdReport_RowCommand(object sender, GridViewCommandEventArgs e)
{
    try
    {
        string TrainingInfo = e.CommandArgument.ToString();


        MS_RITBL objBL = new MS_RITBL();
        //string Mst_Report_Id = string.Empty;
        //string Report_ID = string.Empty;
        //string IsReportLocked = string.Empty;
        //string lockedBy = string.Empty;
        //string due_date = string.Empty;
        if (e.CommandName == "select")
        {
            //lnkReportID.Enabled = false;
            string strMst_Report_Id = Convert.ToString(e.CommandArgument);
            //Session["MST_REPORT_ID"] = Mst_Report_Id;
            //SetToolTip();
        }

    }
    catch (Exception)
    {

        throw;
    }
}

Please Help.

`Binding Grid on IsPostback,` So you are binding the grid when `IsPostback` is true or when it is false? Add the code where you are binding you gridview — Pawan Nogariya, Jun 01 '16 at 12:15
Actually this grid is being shown inside ajax:ModalPopupExtender so no ispostback is coming into picture — rp4361, Jun 01 '16 at 12:19
Ok, but you should still post the code where you are binding it. That can give some idea — Pawan Nogariya, Jun 01 '16 at 12:21
Try after setting `UpdateMode="Always"` property of update panel — KanisXXX, Jun 01 '16 at 12:35

Guys the problem was that labels inside ItemTemplate were having same id accidently so event was blocking up.

Thanks
