Event for databinding of gridTemplate column

[usman]

I want to conditionally bind the images in telerik:template column but the cs code for it never gets executed 

<telerik:GridTemplateColumn  ItemStyle-Width="40px" ItemStyle-Font-Names="Arial" ItemStyle-Font-Bold="true">
    <ItemTemplate>

  <asp:ImageButton ID="vote_up" runat="server"  CommandName="up" />
  <br />
  <%#Eval("likes") %>
  <br />
  <asp:ImageButton ID="vote_down" runat="server"   CommandName="down" />
    </ItemTemplate>
    </telerik:GridTemplateColumn>

the Cs code is 

protected void answer_grid_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridTemplateColumn)
        {
            GridDataItem item = e.Item as GridDataItem;
            ImageButton up_url = item.FindControl("vote_up") as ImageButton;
            ImageButton down_url = item.FindControl("vote_down") as ImageButton;
            if (Eval("expr1").ToString().Equals(cur_mem_id))
            {
                if (Eval("liked").ToString().Equals("TRUE"))
                    up_url.ImageUrl = "~/images/up_no";
            }
            else up_url.ImageUrl = "~/images/up_logo.png";

            if (Eval("expr1").ToString().Equals(cur_mem_id))
            {
                if (Eval("liked").ToString().Equals("FALSE"))
                    down_url.ImageUrl = "~/images/down_no.png";
            }
            else down_url.ImageUrl = "~/images/down_logo.png";


        }
    }

the code in If block never gets executed

Hello Usamn,

Try the following code.
C#:

protected void grid_ItemDataBound(object sender, GridItemEventArgs e)
{
  if (e.Item is GridDataItem)
  {
  GridDataItem item = (GridDataItem)e.Item;
  ImageButton img = (ImageButton)item.FindControl("vote_up");
   img.ImageUrl = "~/images/up_no";
  }
}
