        string ala = ViewState["ala"].ToString();
        string[] arrVal = ala.Split(',');
            
                foreach (GridViewRow row in grdBindExcel.Rows)
                {
                    if (row.RowType == DataControlRowType.DataRow)
                    {
                     
                        for (int i = 0; i <= arrVal.Length-1; i++)
                        {
                            int index = Convert.ToInt32(arrVal[i]);
                            string headertext = grdBindExcel.HeaderRow.Cells[index].Text;
                            string name=row.Cells[index].Text;
                            dt.Rows.Add(headertext);
                        }
                }
            }
                grdviw.DataSource = dt;
                grdviw.DataBind();
           
    }
