switch (btn.CommandArgument)
{
   case "EDIT_RECORD":
        break;
   case "DELETE_RECORD":
        break;
   case "VIEW_RECORD":
        if (recordGuid.ToString() != "00000000-0000-0000-0000-000000000000")
        {   
            string url = "NonexpenditureTransferDetail.aspx?id=" + recordGuid.ToString();
            Response.Redirect(url, false);
            Context.ApplicationInstance.CompleteRequest();
        }
        break;
