when the device culture is changed to Arabic, the date picker does not respect the Hijri calendar

  • on iOS exception is thrown - System.ArgumentOutOfRangeException: Specified time is not supported in this calendar. It should be between 04/30/1900 00:00:00 (Gregorian date) and 11/16/2077 23:59:59 (Gregorian date), inclusive. Parameter name: time 

The DatePicker supports the Gregorian calendar

The control has problems when selecting, overtyping and inserting content.

Type something:

Select all text:

Type "1":

I'd expect the entire existing content to be deleted and new value to be "1".

Same goes for inserting a character:


Attempt to insert "4" between "3" and "5":

"5" is overtyped. Inserting doesn't work.

if you look at the .nuspec file for the Telerik.UI.for.Xamarin.Documents.Flow package there is an entry in the 

<framework> assemblies element;

<frameworkAssembly assemblyName=”WindowsBase” targetFramework=””/ >

This is what causes NuGet to drag the WindowsBase assembly in.

 we cannot build the iOS project - we get the following error.

The type 'NotifyCollectionChangedAction' exists in both 'System, Version=, Culture=neutral, PublicKeyToken=7cec85d7bea7798e' and 'WindowsBase, Version=, Culture=neutral, PublicKeyToken=31bf3856ad364e35'

We are not referencing the WindowsBase assembly directly, but on analyzing the Nuget dependencies we found the following dependency chain;

Telerik.UI.for.Xamarin (2020.3.1106.1) -> Telerik.UI.for.Xamarin.Documents.Flow (2020.3.1019) -> WindowsBase (Framework Assembly)

 it seems that WindowsBase (and PresentationCore which is also included) are not intended for Xamarin iOS or Android applications.

The TabView control should support a swipe event to change the active item. Similar to the ListView with the IsItemSwipeEnabled-property.

When you update the data in the chart so that the vertical axis values are changed - the annotation does not properly update and stays at the same location.

Use the following code:

<StackLayout Orientation="Vertical">
    <telerikInput:RadAutoCompleteView ItemsSource="{Binding Source}"
                                        TextSearchPath="Name" />
    <telerikInput:RadAutoCompleteView ItemsSource="{Binding Source}"
    <telerikInput:RadAutoCompleteView ItemsSource="{Binding Source}"

Steps to reproduce: 

On the first control, enter a value not in the list.
Click in the control to accept the value.
On the second control, enter a value not in the list
Hit the Tab key on the keyboard.
Click on the first control again
Focus bounces around. You must restart the app to fix the issue.

All columns cannot be scrolled with the mouse wheel. Dragging the columns with the mouse kind of works, but extremely slowly, to the point of being unusable; plus, it's not intuitive.

Changing a property on an item that is involved with grouping and sorting and then removing and re-adding the item to the collection results in the list being in an invalid state (e.g. duplicate items, incorrect template, etc.)

Error message can be reproduced on iPhone 11 Simulator iOS 13.6 

[UICollectionView] Invalid update: invalid number of items in section 0.  The number of items contained in an existing section after the update (4) must be equal to the number of items contained in that section before the update (4), plus or minus the number of items inserted or deleted from that section (1 inserted, 0 deleted) and plus or minus the number of items moved into or out of that section (0 moved in, 0 moved out). - will perform reloadData.
