installing the new version of MahApps i've find a very strange behaviour while using a usercontrol that simply contains a listview. The content of the flyout look like this:

        <mhControls:Flyout Position="Top" IsOpen="{Binding IsOpen}" IsModal="False" Theme="Accent" Margin="0,17,0,0">
            <StackPanel Orientation="Vertical">
                <TextBlock Text="My sources list" FontSize="24" Padding="0,10">
                        <DropShadowEffect ShadowDepth="3" />
                <uc:ucAvailableSource Padding="0,30" BorderBrush="Silver" BorderThickness="0,2" x:Name="_availableSrc">
                        <i:EventTrigger EventName="onSelectionChanged">
                            <i:InvokeCommandAction Command="{Binding AvailableSourceSelectedCommand}" CommandParameter="{Binding SelectedItem, ElementName=_availableSrc}" />


What's happens is that when opening the Flyout the list was empty....if i put the same control outside the flyout all works fine, and using the previuos version of MahApps (1.2.4) works fine too.
Any idea ?

  • MahApps.Metro v1.3.0
  • Windows 10
  • Visual Studio 2013
  • .NET Framework 4.6.1
