            DateTime ReportDate = Convert.ToDateTime(DrpDwnReportDate.SelectedValue);
            //DateTime ReportDate = Convert.ToDateTime("2012 / 11 / 16");

            string strTimeStamp = String.Format("{0:MMM d, yyyy}", ReportDate);

            tbx3.Text = App.SelAreaNameSellThru + " " + "WW Weekly Sellin Summary" + "-" + strTimeStamp;

            tbx4.Text = DrpDwnFiscalMonth.SelectedValue.ToString();

            //}

Please provide me any solution
