Above the TreeView there is a Telerik.SegmentedControl, with two segments. If I click on one of the segments the ItemsSource of the TreeView gets updated by using .Add() or Remove() of the ObservableCollection.

If every Segment is called for the first time there is no problem. But if I want to clear all Items and display the empty treeView I get the following Exception.
Java.Lang.IndexOutOfBoundsException: 'Inconsistency detected. Invalid item position 0(offset:-1).state:14 md5a5af569a83c1a3f5c3a8a63bd7d39860.RadExtendedListView{c6376f1 VFED..... ........ 0,0-1200,840 #5}, adapter:com.telerik.widget.list.ListViewWrapperAdapter@b30041b, layout:android.support.v7.widget.LinearLayoutManager@3fd42d6, context:md5db22775bb305bf9756607f4261793d51.MainActivity@1d6cd4f

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.

When longer string is used for HeaderText the text could not be wrapped. Also the issue occurs when using Label with LineBreakMode="WordWrap" inside the TabViewHeaderItem.Content:

<telerikPrimitives:TabViewItem>
    <telerikPrimitives:TabViewItem.Header>
        <telerikPrimitives:TabViewHeaderItem>
            <telerikPrimitives:TabViewHeaderItem.Content>
                <Label Text="Lorem ipsum dolor sit amet, consectetur adttert etertert erterter ipiscing elit." LineBreakMode="WordWrap"/>
            </telerikPrimitives:TabViewHeaderItem.Content>
        </telerikPrimitives:TabViewHeaderItem>
    </telerikPrimitives:TabViewItem.Header>
    <telerikPrimitives:TabViewItem.Content>
        <Label Margin="10" Text="Label" />
    </telerikPrimitives:TabViewItem.Content>
</telerikPrimitives:TabViewItem>

As of the latest release (10/04/2019) RadPieChart with a PieSeries having LabelBinding set to a property name, and ShowLabels set to True, with the list of data bound to ItemsSource containing one or more empty pie slices (a null in the list), causes a System.Reflection.TargetException to be thrown on load of the page containing the chart in iOS (this scenario works fine in UWP).

I am using the latest available Visual Studio 2019 (16.3.5) and the latest available Xamarin.Forms package (4.2.0.848062) and testing on an iPad with iOS 13.1.  The reason I need to have a null value in the list is so that the custom color palette I'm applying will always apply the same colors to the same data points (pie slices), even though in some cases, zero or one or two of the three pie slices will have no data value (and so should not appear in the chart, but still "use up" the corresponding color in the 3 colors of the palette).

In the 08/02/2019 release, this scenario worked fine in iOS (the 09/13/2019 release had the https://feedback.telerik.com/xamarin/1431067-chart-ios-invalidcastexception-is-thrown-when-the-chart-is-loaded issue, which is now resolved in the 10/04/2019 release, but which prevented my testing in iOS since in my app I had RadCartesianCharts on the same pages as the RadPieCharts).

The newly broken functionality in iOS could possibly be related to two other items that are marked completed:
https://feedback.telerik.com/xamarin/1366403-piechart-tooltip-behavior-is-not-working-properly (in 10/04/2019 release)
https://feedback.telerik.com/xamarin/1365842-chart-null-value-support (in R3 2018 SP release)

I have a StackLayout, a ListView and within the listview a RadCheckBox and a Label. The StackLayout has a binding to IsVisible with the viewmodel. The ListView binds IsVisible to another property bound in the viewmodel. When OnAppearing of the Page, the ItemsSource of the ListView is set to an ObservableCollection. Now we get a crash on iOS and a Samsung Galayxy S with Android 9:

The remedy after a lot of trial and error was to replace the ListView with the Telerik ListView. Now the App no longer crashes. I hope this helps investigating the issue, since I noticed there are similar requests in the bug reports. 

I'm using: Xamarin Forms 4.2.0.848062, Telerik2019.3.1004.1.

Column names in column selector are not visible in Android the first time the column selector is shown. This happens only in the case UserFilterMode is disabled.

I've attached a handler to the ViewChanged event of the Calendar component.

The event fires on Android but not on UWP. I've tried changing the view type using the calendar controls and also programatically but the event is not being fired.

We have implemented chat functionality using Telerik RadChat component. The problem is that the scroll functionality doesn't scroll fully to the bottom on IOS. It randomly stops somewhere in between. The same code runs perfectly on Android. Below I have attached an example code of our solution.


<telerikConversationalUI:RadChat 
          BackgroundColor="White" 
          Grid.Row="1" 
          x:Name="chat" 
          Author="{Binding Me}"
          ItemsSource="{Binding Items}"
          AutoScrollMode="Always"
          ItemConverter="{StaticResource SimpleChatItemConverter}" 
          SendMessageCommand="{Binding NewMessageCommand}"
          ItemTemplateSelector="{StaticResource CustomChatItemTemplateSelector}"
          SendMessageButtonImage="ic_send_green">

if the swipe content of the cells are buttons, dragging the buttons up and down will keep the swiped cells in the same position of the screen, creating unexpected animations and showing the entire swipe content of the cell.

When swiping a cell, the swipe content of the cell will be shown if the swipe threshold is reached.  On iOS, the swipe content of another cell can be shown immediately by swiping another cell (which is an expected behaviour).  However on Android, when the user swipes another cell, the swipe content of the other cell isn't shown (while the swipe content of the first cell becomes hidden).  The user has to swipe the other cell again to show the swipe content.

If there is an input control (Editor, Entry) inside the ItemTemplate of the TreeViewDescriptor and its Text is bound to any property of the data item, changing the ItemsSource of the TreeView raises an exception of type AccessViolationException.
