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.
Region.Op.REPLACE is deprecated and therefore the exception is thrown:
[AndroidRuntime] java.lang.IllegalArgumentException: Invalid Region.Op - only INTERSECT and DIFFERENCE are allowed

If there is an all-day appointment at a certain date, navigating to a different date through the week navigation in DayView and going back to the previous date, it will not always show the all-day item.
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.
It would be interesting if the map control could read a shapefile or kml file and visualize the shapes, besides exporting the modifications of the map (shapes) to a shp format.
Currently we are working with Telerik xamarin forms application,We are using radlistview.I want to scroll and select item with up and down arrow keys.Can we have any sample on this.
Thanks & regards
