        {
            //if (ctrl is System.Web.UI.WebControls.Panel)
            if (ctrl is Panel)
            {
                //System.Web.UI.WebControls.Panel pl = (System.Web.UI.WebControls.Panel)ctrl;
                Panel pl = (Panel)ctrl;

                if (pl.ID.Contains("Panel") && pl.Visible == true)
                {
                    foreach (object obj in pl.Controls)
                    {
                        //if (obj is System.Web.UI.WebControls.TextBox)
                        if (obj is TextBox)
                        {
                            TextBox tb = (TextBox)obj;
                            tb.Text = "";
