//try
    //    {

    //          SqlDataSource sds_confirm_date = new SqlDataSource();
    //           sds_confirm_date.ConnectionString = ConfigurationManager.ConnectionStrings["BTI_NEWConnectionString"].ToString();
    //           sds_confirm_date.SelectCommandType = SqlDataSourceCommandType.StoredProcedure;
    //           sds_confirm_date.SelectCommand = "[date_sp_new]";
    //            //sds_confirm_date.SelectParameters.Add(new Parameter("fromdate", System.TypeCode.String, TextBox_addedDate_from.Text));
    //            //sds_confirm_date.SelectParameters.Add(new Parameter("todate", System.TypeCode.String, TextBox_addedDate_to.Text));

    //            //String dtfromdate = null;
    //            //if (TextBox_addedDate_from.Text != string.Empty)

    //            //if (TextBox_addedDate_from.Text == "")
    //            //{
    //            //    sds_confirm_date.SelectParameters.Add("fromdate", System.TypeCode.DBNull, null);
    //            //}
    //            //else

    //            //}
    //            //


    //            sds_confirm_date.SelectParameters.Add(new Parameter("fromdate", System.TypeCode.String, TextBox_addedDate_from.Text));
    //            sds_confirm_date.SelectParameters.Add(new Parameter("todate", System.TypeCode.String, TextBox_addedDate_to.Text));
    //            GridView1.DataSource = sds_confirm_date;
    //            GridView1.DataBind();
    //        }


    //    catch (Exception ex)
    //    {
    //        Label1.Text=ex.Message;
    //
}

but not getting the result for when blank textbox values are pass to store prcedure
