Validation not working on __doPostBack call

[Martin Gartmann]

Hi,

i have a control with multiple input boxes where i need to validate required values.

Following http://www.telerik.com/help/aspnet/ajax/ajxexclude.html i have added a submit button.

When is use in page_load

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If Not Page.IsPostBack Then
            btnStoreCustom.Attributes.Add("onclick", String.Format("realPostBack('{0}', ''); return false;", btnStoreCustom.UniqueID))
        End If
    End Sub

my code code

Protected Sub btnStoreCustom_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnStoreCustom.Click
        ' save all custom made values in Session Variables for future use
        Session("MP1A") = CInt(rntbPM1A.Value)
        Session("MP1B") = CInt(rntbPM1B.Value)
        Session("MP2A") = CInt(rntbPM2A.Value)
        Session("MP2B") = CInt(rntbPM2B.Value)
        Session("MP3A") = CInt(rntbPM3A.Value)
        Session("MP3B") = CInt(rntbPM3B.Value)
        Session("MP4A") = CInt(rntbPM4A.Value)
        Session("MP4B") = CInt(rntbPM4B.Value)
        Session("MP5A") = CInt(rntbPM5A.Value)
        Session("MP5B") = CInt(rntbPM5B.Value)
        Session("MP6A") = CInt(rntbPM6A.Value)
        Session("MP6B") = CInt(rntbPM6B.Value)
        Session("MP7A") = CInt(rntbPM7A.Value)
        Session("MP7B") = CInt(rntbPM7B.Value)
        Session("MP8A") = CInt(rntbPM8A.Value)
        Session("MP8B") = CInt(rntbPM8B.Value)
        Session("MP9A") = CInt(rntbPM9A.Value)
        Session("MP9B") = CInt(rntbPM9B.Value)
        Session("MP10A") = CInt(rntbPM10A.Value)
        Session("MP10B") = CInt(rntbPM10B.Value)
        Session("MP11A") = CInt(rntbPM11A.Value)
        Session("MP11B") = CInt(rntbPM11B.Value)
        Session("MP12A") = CInt(rntbPM12A.Value)
        Session("MP12B") = CInt(rntbPM12B.Value)
        Session("MP13A") = CInt(rntbPM13A.Value)
        Session("MP13B") = CInt(rntbPM13B.Value)
        Session("MP14A") = CInt(rntbPM14A.Value)
        Session("MP14B") = CInt(rntbPM14B.Value)
        Session("MP15A") = CInt(rntbPM15A.Value)
        Session("MP15B") = CInt(rntbPM15B.Value)
        Session("MP16A") = CInt(rntbPM16A.Value)
        Session("MP16B") = CInt(rntbPM16B.Value)
        Session("MP17A") = CInt(rntbPM17A.Value)
        Session("MP17B") = CInt(rntbPM17B.Value)
        Session("Weight") = CInt(rntbGewicht.Value)
        Session("Height") = CInt(rntbGroesse.Value)
    End Sub

is executed but no validating was done. 

In case of excluding the  btnStoreCustom.Attributes.Add

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
       If Not Page.IsPostBack Then
           '  btnStoreCustom.Attributes.Add("onclick", String.Format("realPostBack('{0}', ''); return false;", btnStoreCustom.UniqueID))
       End If
   End Sub

validation is done, but the code is not executed.

My ASPX for the button looks like this

<asp:Button ID="btnStoreCustom" runat="server"
     Text="Diese Daten zwischenspeichern!" PostBackUrl="~/overlay.aspx"
     ValidationGroup="AllPoint" CommandName="Submit" CausesValidation="True" />

Any suggestion on this task ?

Kind regards

Hello Martin,

I would suggest using the EnableAJAX approach, listed in that help document, to disable the Ajax postback. The reason being, you need to add the validation group that it uses to use the real postback approach.

I hope that helps.
