 form code：

            <asp:FormView ID="FormViewClient" runat="server" DataKeyNames="client_id" DataSourceID="ClientsObjectDataSource" OnItemUpdating="client_updating">

       string text = tb.Text;

       System.Globalization.DateTimeFormatInfo dateInfo = new System.Globalization.DateTimeFormatInfo();

       dateInfo.ShortDatePattern = "dd/MM/yyyy";

        DateTime dt = Convert.ToDateTime( text,dateInfo);

        string test = dt.Date.ToString();

       e.NewValues["date_registered"] = dt.Date.ToString();

       TextBox tb_start = (TextBox)FormViewClient.FindControl("licenced_startTextBox");

 

       string text_start = tb_start.Text;
