We are experiencing a hard crash when updating a collection that is the source for a RadListView.   This appears to only occur in Android 10 on Samsung device with Bixby Button enabled.

when applying custom label formatter to wrap the categorical axis label text, the text is not wrapped. It works fine on iOS and UWP.

If you have the following PieChart with donut series definition:

<telerikChart:RadPieChart HeightRequest="200" 
        <telerikChart:DonutSeries ShowLabels="True"
                                  ItemsSource="{Binding Data}" />
        <telerikChart:DonutSeries ShowLabels="True"
                                  ItemsSource="{Binding Data1}" />

On android works as expected:

On iOS the series are overlapped and not visualized as expected. The radius factor is not respected

On UWP the second donut series in not visualized and the radius factor is not respected.

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 CANCEL text wraps to a second line on most of the Android devices. For example Hisense F20 (720 x 1280) and Huawei P9 Lite (1080 x 1920).

The issue occurs when new Telerik project is created (or create Xamarin.Form new project, add the Telerik UI for Xamarin assemblies manually and then add some of the Telerik UI for Xamarin Item Templates.

All platform projects are including assemblies from the Portable. For example for the Android project assemblies should be included from the Android folder. 

Also this issue affects the simple login template - for example the entry controls for user name and password are not visible.
UWP it complains that the common.dll is missing even though that reference is present. I manually removed and added it to see if it resolves the issue with no luck.


add the Telerik UI for Xamarin suite using the Telerik UI for Xamarin Nuget Server.

Setting DataFormPasswordEditor inside a custom renderer on Android leads to the following exception:

Java.Lang.NullPointerException: Attempt to invoke virtual method 'java.util.Iterator java.util.ArrayList.iterator()' on a null object reference

 If you create a login page, username password, and you run the app on the debugger, if you close the app using the debugger on visual studio the app closes and the keyboard stays displayed in the android main screen.

If DataGrid is placed inside Grid Row with "*" Height inside RadPopup, the layout of the control is broken when user enters edit mode.  As soon as the keyboard is shown, the DataGrid disappear.

When the Start and EndDate properties are changed one after another and each of them calls PropertyChanged the appointment does not render accurately. If for example there is an appointment from 3 PM to 4 PM (duration 1 hour) and the Appointment is changed to one hour earlier (from 2 PM to 3 PM) on the screen the Appointment is displayed from 2 PM to 4 PM (duration 2 hours).

After I set the DateTime to a specific time and then do clearSelection on it, I can not set the same DateTIme on it. If I set a different DateTime from the original value then it works. Its almost like its ValueChanged Event is not fired or something after ClearSelection is called.

The same issue can be reproduced when using the ClearCommand.

Hi, I checking DateTimePicker control, and I'm not sure if it's bug of feature.

I have picker control bound to nullable DateTime property.
DefaultDisplayDate is bound to DateTime.Now, for help select date in spinner when selectedDate is null.

But in such situation select today date from spinner not change anything, I suppose that date change event not fire.

01.<telerikInput:RadDateTimePicker Grid.Row="7" Grid.Column="1"
02.              x:Name="dtxProdDate"
03.              PlaceholderLabelStyle="{StaticResource PlaceholderLabelStyle}"
04.              DisplayLabelStyle="{StaticResource DisplayLabelStyle}"
05.              TabStripItemStyle="{StaticResource TabStripItemStyle}"
06.              SelectedDate="{Binding TestObj.NullableProdDate}"
07.              DisplayStringFormat="yyyy-MM-dd"
08.              SpinnerFormatString="yyyy-MM-dd"
09.              DefaultDisplayDate="{Binding TodayDate}"
10.              Placeholder="Select date..." />

When you try to navigate from a page while the popup is open and there are bindings inside it, a "NullReferenceException: Object reference not set to an instance of an object" is thrown.

If the series is added after the page constructor, the vertical axis labels are not shown.

As a workaround, create the series in the constructor and set its ItemsSource at a later stage.

The Chart loses all the UI customizations made in the iOS platform renderer when the Series are updated, for example, if you show/hide certain Series or updated their ItemsSource.

Currently the first label marking the DayStartTime is not visualized in the timeline of the DayView (and MultiDayView) on Android. This leads to inconsistency with iOS, where the first label is displayed.

In Android when an Entry is focused (and probably not only Entry) and you press Enter and expect to automatically tab to the next editor - it does not work. Sometimes the focus is not moved, sometimes the focus is moved to an invalid location like the first editor in the DataForm or an Entry outside the DataForm.
