If you have the following PieChart with donut series definition:

<telerikChart:RadPieChart HeightRequest="200" 
                          WidthRequest="200">
    <telerikChart:RadPieChart.Series>
        <telerikChart:DonutSeries ShowLabels="True"
                                  ValueBinding="Value"
                                  ItemsSource="{Binding Data}" />
        <telerikChart:DonutSeries ShowLabels="True"
                                  RadiusFactor="0.45"
                                  ValueBinding="Value"
                                  ItemsSource="{Binding Data1}" />
    </telerikChart:RadPieChart.Series>
</telerikChart:RadPieChart>

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.

Workaround:

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

When RadPdfViewer is used in a master-detail page, I should maintain the previous page index when I traverse between pages.

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

MaskedInput ignores VerticalOptions

For example the control ignores IsTabStop and TabIndex properties for keyboard tab navigation. It behaves differently on Android, iOS and UWP.

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.

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

xamarin forms on wpf is now official, https://docs.microsoft.com/en-us/xamarin/xamarin-forms/platform/wpf
we need to support telerik on there aswell..

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.

Hi,

I am using DataForm for my project and in the process of implementing validation. For validation, I use DataAnnotation-NonEmptyValdator for the required fields.

Is there a way to change it dynamically in runtime?.

For example, I have 2 fields, the first field is always required. However, the second field is not always required, it depends on the selected item of the first field.

Thanks

Dan
