Try This

protected void grdItems_DataBound(object sender, EventArgs e)
    {
        Boolean hasData = false;


        for (int col = 0; col < grdItems.HeaderRow.Cells.Count ; col++)
        {


            for (int row = 0; row < grdItems.Rows.Count; row++)
            {


                if (!String.IsNullOrEmpty(grdItems.Rows[row].Cells[col].Text)
                    && !String.IsNullOrEmpty(HttpUtility.HtmlDecode(grdItems.Rows[row].Cells[col].Text).Trim()))
                {


                    hasData = true;


                    break;


                }


            }




                 if (!hasData)

                {

                    grdItems.HeaderRow.Cells[col].Visible = false;

                    for (int hiddenrows = 0; hiddenrows < grdItems.Rows.Count; hiddenrows++)

                    {

                        grdItems.Rows[hiddenrows].Cells[col].Visible = false;

                    }



                }



            hasData = false;


        }
