When the IsOpen is set initially to true, on iOS the main content overlay does not display:

For Chart with ScatterLineSeries, in case the ItemsSource contains points with following sample horizontal values: 0, 2, 4, 6, 8, 6, 4, 2, 0, ZoomBehavior does not work correctly on iOS  - when ZoomMode is set to "Both", the  points are taken in incorrect order and the result is a zig-zag chart.

When Group Header template is used and the visibility of an element in the template is changed, the template does not recreate as expected. 

For example add entry /editor in the template and change its visibility

On iOS the editor/entry overlaps the group header and cannot type in it.

On UWP : The editor is visualized as expected but then we change its visibility to false, the space for the editor is still visible. The group header does not layout as expected.

Solution:

You have to collapse/expand the group header so the template in the group header to layout as expected

Telerik.UI.for.Xamarin NuGet package is missing Telerik.UI.for.Xamarin.Documents.Fixed.FormatProviders.Image.Skia package reference.

There is a slow performance when scrolling, expand/collapse items when the ListView Groups are sticky and GroupHeaderTemplate is used. 

Workaround: 
1. Set IsGroupHeaderStickty to false. 

or

2. Use the default group header template

Do you have plans to develop controls for the UNO platform?

 

There are other companies that have already stated that they are working on it, for example,  

https://www.syncfusion.com/blogs/post/collaboration-syncfusion-uno-platform.aspx 

When a popup is attached to a content page with a PresentationMode of modal the popup does not show when binding changes on iOS.  It does work on Android.

For example inside the popup on first place the time selector could be defined.

All parts of the TreeViewItem (indicator, text, checkbox) are defined as one big template. Therefore customization of only one part of the template still requires retemplating the whole item. 

When retemplating is applied to the treeviewitem and  20+ children in the nodes are loaded, the result is as follow: If you run that on iOS and expand a node you'll see that it crunches the UI for a few seconds and then loads the child nodes, but i also see on our application that it will crash some times and either way gives a bad feel to the UI on iOS

When there are items in the Figures collection of a RadPathGeometry, and the Clear() method of the collection is called - an exception is thrownl.

When placing and RadEntry in Popup, Object disposed exception is thrown. 

The issue cannot be reproduced with Telerik UI for Xamarin version 2022.2.624.1

Workaround until a fix for this issue is provided: 

1. Use Telerik UI for Xamarin version 2022.2.624.1

or:

2. Use Xamarin.Forms Entry instead.

The ListView items are not rendered correctly when manual load on demand is used.

The ComboBox SelectedItems are not displayed in the input, when binded dynamically inside RadListView cell and navigation is performed. 

Currently there are areas in the MultiDayView that cannot be styled using the background color.  Provide an option to set a background color to the entire the MultiDayView:

Expose an option to change the indeterminate indicator's width

when setting a TimeLineBackgroundColor to MultiDayView,  it is not respected on iOS. https://docs.telerik.com/devtools/xamarin/controls/calendar/images/calendar_scheduling_timeline.png The image in the middle is on iOS. The timeline background color is not applied

Add support for range series. The series are available in the native charts
Android - RangeBarSeries 
iOS RangeBar and RangeColumn Series
UWP RangeBar, Range Series.

Please add these series to Chart for Xamarin.Forms. 

Null Reference Exception is thrown when the ListView is initially grouped with more than 1 group descriptor and then the control is populated using Range Observable collection. 

When changing the CurrentUICulture to a culture which requires comma as decimal separator (for example, German) - pressing the comma key does not work. You must press period. When pressing period "." -> "," is entered.
