Release R2 2019

If you have a more complex HeaderTemplate containing input controls, each button placed after a certain position does not fire its Click event.  If a button is placed at the top of the template, it functions properly.

I have a class, a collection of which is displayed in RadListView. If the class has a static property, no single item is displayed in UWP. In Android and iOS it works without this problem.

In a scenario when LoadOnDemandMode is Automatic, SpanCount >1 and ItemLength is large the loading indicator has different size depending on its position in the columns, as it takes up all of the available space.

When we use the ListViewGridLayout as LayoutDefinition swiping (neither left or right) is working and the user could not swipe to visualize the swipe content.

ListView throws a System.ObjectDisposedException on iOS when navigating to a page containing the control. The exception is consumed, so it does not crash the app.

FooterTemplate is not displayed correctly

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 an ItemTemplateSelector is applied to the ListView, the item must be refreshed on each property change, to give the ItemTemplateSelector a chance to re-evaluate its logic. This causes the item to flicker on iOS, because it appears with its default size initially, and then it gets resized during the measure/layout phase. Specifying a fixed ItemLength in the LayoutDefinition can work around the problem, if dynamic item sizing is not needed.

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

The control listen for changed to re-filter, so when any property is updated, there is a side effect on iOS - the entry used for editing loses focus.

Currently, the behaviors differ in Android/iOS and UWP. In UWP you can have an empty collection and the LoadOnDemand will trigger when you open the page with the ListView, in iOS/Android you need to have some items in the collection for the LoadOnDemand event to trigger.
