Occasionally the DataGrid horizontal scrolling does not work properly after changing its ItemsSource.  Still, tapping on any item, make it possible to scroll again.

When you have declared a RadTabView with a single item and you try adding items at runtime - the new TabViewItems are added to the Items collection of the control but the UI is not updated.

As a workaround you could set TextColor property of the Entry control.

Reordering items with scrolling do not raise ReorderEnded event

Calling TreeView's CheckItem method when the control is loaded, so that you mimic a "pre-checked" TreeView results in NullReferenceException in RadTreeView.Checkbox ToggleItem method.

Padding and HorizontalContentAlignment are not properly applied when Image is used.

A great first effort! Many thanks!
After some use I do have these suggestions:

1. When User changes LayoutMode the ZoomLevel property changed event should also be fired. I have a Numeric Textbox to adjust viewer ZoomLevel and would like to see its text update on a LayoutMode change. However when LayoutModeChanged fires the ZoomLevel has not yet changed nor does ZoomLevelChanged later fire.
2. The toolbar item for Fit to Width should be a Toggle in all cases, i.e. toggling between Fit Width and Fit Height (or Fit Page) and should be effective at all times (sometimes has no effect if LayoutMode changed to Single Page).
3. The toolbar item to toggle LayoutMode should honor an assignment of its text property.
4. I'm currently using the change in VisiblePagesCount to determine the document is visible. However a "Loaded" event might be even better.
5. I would like to release the viewer's memory of the document before closing the XAML page. An Unload command would be helpful. For now I just assign Source = null.

Support for FileDocumentSource

Ref# 1106424. We are using Kendo Scheduler in our Web application to show the recurring appointments. Similarly, We need the Recurring appointments to the RadCalendar for Xamarin.Forms in Mobile to aligned with Android and IOS.   

Add support for header and footer that scroll with the content of the list view.

StrokeColor and Labels colors are not properly mapped in native Chart.

When the language of the iOS devices is changed to "Right to Left" the SuggestionView is not shown correctly. 

Two of the bar series used CombineMode="Stack" and one - CombineMode="Cluster". The BarSeries with CombineMode="Cluster" overlaps the series with CombineMode="Stack".
