This can be reproduced in the SDK examples ->ListView -> Gestures -> CellSwipeEvents. 1. Change the content of the items so that they have uneven height 2. Scroll down 3. Delete an item by swiping -> Expected result : The items re-arrange correctly -> Actual result : The item is deleted but the ListView is scrolled up when the UI is updated
When LoadOnDemand event have loaded its data then there is some kind of jumping down through the new items while scrolling.
If EndItemSwipe() is called inside the ItemSwiping event handler, the ItemSwiping event continues to occur on iOS until the user physically ends the swipe gesture.

It works on Android and iOS, but on UWP it is defaulting to Explicit mode and clicking the load button crashes the app.
When RadListView is setup to load its items on demand and the LayoutDefinition is GridLayout with SpanCount set to 2 or more, the Footer Template does not take all the width, it expands only to the Width of the first column.
Currently groupheader can be stretched by using GroupHeaderLength property instead rather than resolving it automatically.
The following exception is thrown when scrolling ListView with Grid layout with many columns and rows: Windows.UI.Xaml.LayoutCycleException: Layout cycle detected. Layout could not complete.
The bug can be reproduced on iOS 13 only. It is not reproducible on earlier versions of iOS. Run the attached project on iOS 13 device or Simulator to reproduce it.
Sometimes when focusing an entry and the onscreen keyboard shows up, the ListView is not scrolled correctly, so the entry is overlapped by the keyboard. The ListView layout appears messed up after that and the scrolling does not behave correctly.
Hi,
I rolled my app with the ListView out to production and are getting 8+ crashes a day from 140 users with the above issue. I have included a stack trace. I cannot find the steps to reproduce the issue in development. I have rolled back to using the native ListView as this does not crash the app.
Attached is an example project to see what I am doing in general terms, but I have not been able to reproduce this crash in it.
My guess is that a DataTemplate is not being cleaned up properly and when the data behind is changed it attempts to access the control that represented the data in the DataTemplate.
Regards
Anthony
