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>

When you try to swipe several items at once by using more than 1 finger - the items are stuck and the space where the ItemSwipe content should be present is left blank. The issue can also be observed if you swipe items very fast.

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 the ListView has more items, it could be vertically scrolled, however, there is no UI for vertical scrollbar on Android.  The same can be observed with RadTreeView control.

Java.Lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

For example change the IsPullToRefreshEnabled state on button click, when button is pressed several times, exception is throw.

Follow this tutorial https://docs.telerik.com/devtools/xamarin/controls/listview/listview-features-load-on-demand#loading-mode-with-collection 

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.

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.
