Layout Issues

ScrollTo Issues

What went well?

How easy is it to convert your existing ListView to the CollectionView?

• very easy, basically copying the "ViewCell" XAML to the "DataTemplate"

What didn't go well?

There are three major issues:

• Layout issues for complex variable height scenarios, most cases are handled well but some not
• ScrollTo misses sometimes the right location for complex variable height scenarios
• When starting the App in landscape mode, screen rotation doesn't expand the CollectionView correctly. Adding "FillAndExpand" options to StackLayout or CollectionView doesn't solve the
  problem.
• Changes in the "ObservableCollection" are not reflected. Press the "Clear button" in the toolbar and nothing happens.

How is the performance?

How is the performance using CollectionView compared to when using the ListView?
