        BackColor="White" BorderColor="#CC9966" BorderStyle="None" BorderWidth="1px" 
        CellPadding="4">

    </Columns>



      conn.Open();
             SqlDataReader rdr = comm.ExecuteReader();
             if (NAME.Equals("admin"))
             {
                 GridView1.DataSource = rdr;
                 GridView1.DataBind();
             }
             else
             {
                 GridView2.DataSource = rdr;
                 GridView2.DataBind();
             }
             rdr.Close();

add onRowCommand event to your grid

OnRowCommand="OnRowCommand_GridView1"

Then define a Button link with CommandName and CommandArgument

      <asp:LinkButton ID="lnk1" runat="server" Text="DoClick"  CommandName="Select" CommandArgument='<%#Eval("FileID") %>'></asp:LinkButton>

not by code

protected void GridView1_OnRowCommand(object sender, GridViewCommandEventArgs e)
    {

       if (e.CommandName == "Select")
        {
          int MyFileID = e.CommandArgument;
       //Now Perfrom here ur desired action
       }

Hope this helps you.
