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/

The staggered layout lays out items in a staggered grid formation. the layout is available as follow:

Telerik Ui for Xamarin.iOS ListView

Telerik UI for Xamarin.Android ListView

Telerik UI for UWP ListView

On UWP and Android the item can be swiped beyond the SwipeOffset property. Add option to restrict the swiped distance to the SwipeOffset value.

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.

Provide API which enables the group headers to remain in the view when scrolling until the next ones push them away.

The BorderLocation property of ListViewItemStyle seems to either not be working correctly, or is severely limited in its capabilities.  Although the Location enum is not marked with [Flags], the values 0, 1, 2, 4, 8, 15 seem to imply bit flags that should be able to get OR'd together. However, when trying to use Location.Top | Location.Bottom, the result is NO border at all.

Example:

    public class BorderLocationExample : ContentPage
    {
        private readonly ListViewItemStyle BorderAll = new ListViewItemStyle
        {
            BorderColor = Color.Blue,
            BorderLocation = Location.All,
            BorderWidth = 8
        };

        private readonly ListViewItemStyle BorderTop = new ListViewItemStyle
        {
            BorderColor = Color.Blue,
            BorderLocation = Location.Top,
            BorderWidth = 8
        };

        private readonly ListViewItemStyle BorderTopAndBottom = new ListViewItemStyle
        {
            BorderColor = Color.Blue,
            BorderLocation = Location.Top | Location.Bottom, // <-- DOESN'T WORK !!!  These items have NO border at all.
            BorderWidth = 8
        };

        public BorderLocationExample()
        {
            BackgroundColor = Color.Gray;

            var items = new ObservableCollection<string>
            {
                "Item 1",
                "Item 2",
                "Item 3",
            };

            Content = new StackLayout
            {
                Orientation = StackOrientation.Vertical,
                Children =
                {
                    new RadListView
                    {
                        ItemsSource = items,
                        ItemStyle = BorderAll
                    },
                    new RadListView
                    {
                        ItemsSource = items,
                        ItemStyle = BorderTop
                    },
                    new RadListView
                    {
                        ItemsSource = items,
                        ItemStyle = BorderTopAndBottom
                    },
                }
            };
        }
    }
