I have mui:ModernFrame that gets loaded with usercontrols when certain buttons are clicked;
Button
<Button Command="NavigationCommands.GoToPage" CommandTarget="{Binding ElementName=Frame}" x:Name="HeadWidget" FontSize="14" Margin="0,10,0,3" Content="Head Widget" Style="{StaticResource LinkButton}" />
Frame
<mui:ModernFrame x:Name="Frame" Source="/Pages/Projects/Views/Overview.xaml" Panel.ZIndex="999999" />
Code behind to update Frame (on button click)
EditPage.CommandParameter = "/Pages/Projects/Views/Edit/Pages/EditPages.xaml#" + valueFromPage1;
Which works well, even animates the new content into the frame, but the elements/items (ie buttons, TextBoxes etc) inside the UserControl that is loaded into the frame are not focus-able or clickable.
Any reason why this would be the case, I have tried adding buttons in the demo of the FirstFloor mui ModernFrame sample and has the same effect
