Question

I am working on a Metro Style App for Windows 8. If I go to the start screen and back to my two main pages, they freeze.

The simpler of the two pages contains only a text box, a button, a few text blocks, and a few hyperlink buttons. The text box displays and sets settings.

I have no code in the resuming or suspending events, and the resuming event doesn’t fire anyway.

Nothing unusual appears in the debugger. A new blank page works fine on resume, but upon copying the xaml from the old pages, the problem continues. Has anyone experienced this problem before. I understand this is not much information, but I cannot find any additional details.

Answer 1

For anyone having the same issue, I found the solution. The problem was in the c#, not the xaml. I used Dispatcher.RunAsync to run the same method over and over again.

void Animate()
{
    ...
    Dispatcher.RunAsync(CoreDispatcherPriority.Normal, new DispatchedHandler(Animate));
}

I used a DispatcherTimer instead, and it fixed the problem.
