Window transparent after properties set in viewmodel #28
Description
Hi EmptyKeys, Im am using your great framework for a game and want to create a animated caroussel
in a window. The storyboard animations are working great in the root window, but when used in a window then all the UI becomes transparent and loose their borders and titles after i click on a button shift left/right.
This is caused in the viewmodel on caroussel button click wher multiple properties are set.
Any Idea what is going on? and what can i do to prevent this behavior
Xaml:
<DataTemplate DataType="{x:Type data:PanelSelectProfile}">
