ListViewLoadOnDemandCollection method is not triggering in iOS automatically when there is a need to display the items on the screen. We have to manually scroll the list view then the ListViewLoadOnDemandCollection triggers and give further data to show.
Things are working fine on Android platform.
The LoadOnDemandItemTemplate's HorizontalOptions setting is ignored on Android, it will always be left aligned. See this screenshot for comparison of 3 target platforms side-by-side: https://www.screencast.com/t/K5oWBcP0dLQM The DataTemplate is as follows: <telerikDataControls:RadListView.LoadOnDemandItemTemplate> <DataTemplate> <Grid BackgroundColor="Red" HorizontalOptions="End"> <Label FontSize="24" HorizontalOptions="End" Text="Load more items" TextColor="Black" /> </Grid> </DataTemplate> </telerikDataControls:RadListView.LoadOnDemandItemTemplate>
As soon the user tries to swipe more than one list item at the same time on iOS, the swiping functionality is not properly handled/
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.
