Hi!

We are using your component SlideView on Main Page of our app. Unfortunately when we upgraded Xamarin Forms to 4.0 version we are facing exception - System.NotSupportedException: Unable to activate instance of type Telerik.XamarinForms.PrimitivesRenderer.Android.SlideViewRenderer from native handle 0x75 (key_handle 0x60775bd). ---> System.MissingMethodException: No constructor found for Telerik.XamarinForms.PrimitivesRenderer.Android.SlideViewRenderer::.ctor(System.IntPtr, Android.Runtime.JniHandleOwnership) ---> Java.Interop.JavaLocationException: Exception of type 'Java.Interop.JavaLocationException' was thrown.

 

Steps to reproduce:

1) Open app with SlideView and BottomNavigationBar

2) Navigate to any another tab

3) Back to main page tab

4) App is crashing with this exception.

 

It could be important information to reproduce this but it doesn't happend on every tab. We have five tabs in app (Main Page and 4 additional) and it crashes only on navigation between main page and last tab.

I guess that could happend when SlideView disposes or reloads.

The scenario in which the issue is reproducible is when one of the tabs of a RadTabView contains a RadSideDrawer. Switching the view a couple of times causes an exception to be thrown when trying to open the tab that contains the RadSideDrawer. 

The issue is reproducible in UWP and Android.

Available in minor release 2018.1.0315. It will also be available in the R2 2018 release.

When using a RadListview with a Grid or a Stack Layout in iOS I get the following exception. I haven't tested using the stacklayout outside of the RadListView nor have I tested it outside of the ItemTemplateSelector


Telerik.XamarinForms.Common.NotRegisteredRendererException: There is no renderer registered for the specified type: Xamarin.Forms.Grid
It works fine on Android. Below is the xaml I'm using.

When RadListView is placed inside a TabViewItem content of the RadTabView control,  it does not preserve its SelectedItem, scroll position and expanded items (if it is grouped).

When you have longer text shown in TreeView items and it is wrapped in 2 or 3 rows, the text is clipped incorrectly.

When the ListView has more items, it could be vertically scrolled, however, there is no UI for vertical scrollbar on Android.  The same can be observed with RadTreeView control.
