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.

Flickering occurs after the RadListView is refreshed. The issue is observed with v 2019.1.116.1 of Telerik UI for Xamarin.

An exception is thrown when building in Release with Xamarin.Forms 3.5. 

When LoadOnDemandMode is set to "Automatic" and LoadOnDemand event is used to load items asynchronously, the event is fired multiple times with a single gesture.

Images loaded from memory stream behave strange - on iOS they don’t load immediately, only after list is scrolled and after that they start resizing and reordering randomly when scrolling; on UWP they load on initialization but have same problem with reordering.

RadListView item height is not adjusted to fit the content in the cell on iOS 13 Beta.

An exception on iOS is thrown when the ItemTemplateSelector uses DataTemplate with custom cells

Currently groupheader can be stretched by using GroupHeaderLength property instead rather than resolving it automatically.

With iOS 16 some changes are introduced to the UICollectionView. This breaks the layout of the ListView with dynamically sized items.

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

The LoadOnDemandItemTemplate's HorizontalOptions setting is ignored on Android, it will always be left aligned.

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>

Available in the 2018 R2 SP release.

When RadListView is placed inside a TabViewItem content of the RadTabView control,  it does not preserve its SelectedItem, scroll position and expanded items (if it is grouped).

With the previous release (2018.3.1) displaying many items (10000+) with groups and sorting took less than a second. With the latest release (2019.1.1) the time is increased to several seconds on the same device.

When you have Automatic LoadOnDemandMode enabled and use LoadOnDemand event to load the items,  the event is fired multiple times unnecessarily.

With Automatic LoadOnDemand, once all items are loaded and IsLoadOnDemandEnabled is set to false, when I scroll till the end the loading indicator keeps flickering on knowing that no more items are called.

GroupHeaderTemplate has a default gray background applied and setting Transparent does not take any effect.

If you have set a custom LoadOndemandItemTemplate when the ListView is in manual LoadOnDemand mode, once you click the Load More button - it gets invisible. Clicking on the area where the button should be is working, though.

Available in the R2 2018 release.

System.ArgumentNullException(Value cannot be null) is thrown when item from the listview is selected and the groups are expanded/collapsed.
