Pivot control GiveFocusTo crash

Question

I have a Windows Phone 8.1 application which I am trying to port to UWP. I have a custom control which uses pivot control to show the months in the calendar (each month being a separate pivot item). Now, in some scenarios (when I tap different dates in the month and swipe to the next pivot item) it crashes without throwing any exception (I enabled all the exceptions in exception setting windows of VS). Also, it does not get caught in the application level unhandled exception handler. So, I ended up using crash dumps to analyse the situation and found out that it is throwing exception somewhere internally inside the Windows.UI.Xaml.Phone.dll Below the the stack trace from the crash dump analysis:

Can you please post some code? Did you change the default style of the pivot in windows phone 8.1 app, and copy it into uwp app? — Grace Feng, Jun 02 '16 at 02:33
Yes. Thanks for the hint. I disabled some styles and it fixed the issue :) — tavier, Jun 02 '16 at 07:17
You're welcome, the styles and resources are based on the SDK, they might be different between different version of SDK. If you want to override the style, you can try using the new one for windows 10, version 1511. You can refer to [Default control styles and templates](https://msdn.microsoft.com/en-us/library/windows/apps/mt299122.aspx). — Grace Feng, Jun 02 '16 at 07:29
