Do you mind providing a sample of your scenario? Testing the issue in a simple scenario to show UXDialogBox object using DialogBoxServiceProvider, I could not procude any error. Here is the snippet:

    Private Sub UXPage_Loaded(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles MyBase.Loaded
        DialogBoxServiceProvider.Show(New UXDialogBox1(), Nothing)
    End Sub

need help trying to pop up dialog box (VB) - error in method below (taken from DialogBoxServiceProvider)

Public Shared Sub Show(ByVal modalWindow As IModalWindow, ByVal resultCallback As Action(Of DialogResult))

Dim element As FrameworkElement = DirectCast(ISFocusManager.GetFocusedElement(), FrameworkElement)

Dim owner As IWindow = Nothing

If Not IsNothing(element) Then

Dim logicalContainer As DependencyObject = ISFocusManager.GetLogicalContainerScope(element)

If (TypeOf logicalContainer Is IWindow) Then

owner = DirectCast(logicalContainer, IWindow)

End If

modalWindow.ShowDialog(owner, resultCallback)

End Sub

I get an error that 'owner' is nothing on this line below (which it is)....

modalWindow.ShowDialog(owner, resultCallback)

But in c# sample code below (MVVM example) does not cause the same error..

IWindow owner = null;

Any ideas, thanks
