WPF Application page navigation

Last Modified: 2013-11-12
Hi Experts,
I am new to WPF (know windows forms) and still struggling with some of the basics. Please be kind and be very clear with your assistance.
I have created a main window and added a ribbon with buttons.
I now want to open (show) a page (window) based on button click.
On the page I want to get user input and return the values.
Very basic stuff in winforms. Not so easy in WPF (it seems)
I am using Visual Studio 2010 (Visual Basic)

Hello
You need to use "PageFunction" instead of "Page".
In this case you are able to get result using OnResult event of PageFunction.

Hi
Thank you for your response.

My code is as below, attached find error image:

Class MainWindow
Public ReadOnly Property NavigationService As NavigationService
        Get
        End Get
End Property

Private Sub RibbonButton3_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles RibbonButton3.Click
        Dim pageFunctionUri As New Uri("SetupCriteria.xaml", UriKind.Relative)
        Me.NavigationService.Navigate(pageFunctionUri)
    End Sub
End Class
Capture.PNG
Use NavigationPage instance as "Navigate" function parameter instead of Uri

Something like

Dim page as New SetupCriteria();
page.OnResult += ResultHandlerFunction;
Me.NavigationService.Navigate(page);

Forgive my 'blondness'
I am not winning with the syntax (or something)

Private Sub RibbonButton3_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles RibbonButton3.Click
        Dim page As New SetupCriteria()
        page.OnResult += ResultHandlerFunction
        Me.NavigationService.Navigate(page)
        End Sub

Please see image

Did you define ResultHandlerFunction handler?
