The issue occurs on the following device:

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 building against XF5 and after migrating a project you can get the following error:-

Severity Code Description Project File Line Suppression State
Error failed linking file resources. App1.Android
Error '5dp' is incompatible with attribute verticalOffset (attr) float [weak]. App1.Android
Error '10dp' is incompatible with attribute horizontalOffset (attr) float [weak]. App1.Android

It appears to be a conflict between

    <PackageReferenceInclude="Xamarin.Google.Android.Material"Version="1.2.1.1" />
and Telerik assemblies.
If a dummy app is built with that Nuget it all works fine until the Nuget
<PackageReference Include="Telerik.UI.for.Xamarin" Version="2021.1.119.1" />
is added.
So you can have one or the other but not both.
Please see this GitHub thread where its discussed more and a sample app is posted.

Barcode reader which can scan a barcode and input it in an entry.

DataBindingComplete event of the DataGrid should be fired when the associated data (ItemsSource) has been successfully bound to the control or any data operation like Group, Sort or Filter is applied.  Currently the event handler is not called as expected.

     <telerik:RadBusyIndicator
                HorizontalOptions="FillAndExpand"
                VerticalOptions="FillAndExpand"
                IsBusy="{Binding IsBusy}"
                IsVisible="{Binding IsBusy}"
                AnimationContentHeightRequest="60"
                AnimationContentWidthRequest="60"
                AnimationType="Animation3"
                AnimationContentColor="{DynamicResource BrandPrimaryColor}">
                <telerik:RadBusyIndicator.BusyContent>
                    <Label Text="{Binding BusyContent}" HorizontalOptions="Center"/>
                </telerik:RadBusyIndicator.BusyContent>
      </telerik:RadBusyIndicator>

RdBusyIndicator BusyContent data binding does not work for the above Label inside the "telerik:RadBusyIndicator.BusyContent". If a string constant is assigned to the Text(for example "Loading..."), then it works perfectly.

The view model 100% has the property "BusyContent" with a value. By the way, the IsBusy and IsVisible data binding work fine.   

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..

Combobox, selection mode multiple.

Select the third item:

And you get this:

(also note the +1 circle going over the border)

However, set selected items programatically, and you get this:

There's plenty of space in the control.

Open the dropdown:

Still plenty of space, but... the button has disappeared.

Collapse it by clicking somewhere outside the control and you get back to the measurement bug:

Hi Team,

Were are using RadCalendar- Agenda View mode.

In that

a)we have to add an icon in some specific appointments. 
b)We also need a clicked event on that icon  to show a TOOL-TIP with some details in it. 

Have attached a snapshot for your reference.

Please let it know the possibilities

Thanks,

There seems to be 2 issues with Telerik ui for xamarin and Xamarin.AndroidX.Core versions 1.3.2.2 and newer where A) Linker seems to be failing when set to "Sdk Assemblies Only" on Visual Studio 16.9.0.

The other issue is with Telerik RadListView and same  AndroidX.Core at runtime I am getting the following exception:

System.TypeLoadException: 'VTable setup of type Telerik.XamarinForms.DataControlsRenderer.Android.ListViewAccessibilityDelegateCompat failed'

Please advise

Please refer to this issue: https://feedback.telerik.com/xamarin/1509502-errors-with-latest-versions-of-androidx
