protected void cmdDelete_Click(object sender, EventArgs e)
       {
          diabList = (List<DiabeticFields>)(Session["DiabObject"]);
               CheckBox chk = new CheckBox();
               foreach (GridViewRow gvr in grdDocOrders.Rows)
               {
                   chk = (CheckBox)(gvr.Cells[0].FindControl("chkSelect"));
                   if (chk.Checked == true)
                   {
                       diabList.RemoveAt(gvr.RowIndex);
                   }
                   Session["DiabObject"] = diabList;
                   if (diabList != null)
                   {
                       grdDocOrders.DataSource = diabList;
                       grdDocOrders.DataBind();
                   }
                   else
                   {
                       emptyGridFix();
                   }
               }
