Same issue here when navigating back to the frame that contains my grid (everything else is properly refreshed). Moving the scrollbar or resizing the window triggers a refresh of the grid...

Hi Joe,

Yes I have try this too ! 

 I can provide you a non-obfuscated version of the .exe with instructions...

Here is how I navigate : 

List<Page> pages = ... 

 navigationFrame.Navigate(currentPage);

Here is the code initialization in the page:

 xdgGenres.DataSource = MediaKernel.CurrentMediaDeviceFeature.Medias;

 Here is the XAML code :
