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..

In Xamarin Forms there is a serious need for a Rich Text Editor control that would allow you to do this such as highlight text, apply fonts, styles etc. I think a tool like this is in great demand among Xamarin developers. Currently there are some Open source controls that have implemented these features however they have not been maintained and cannot be relied on for enterprise solutions

The image editor is a great start, but missing a critical feature - image drawing / annotation. The ability to draw lines, shapes or text onto an image. Should allow this to be done when pinch / zoom is in progress. Items drawn should be amendable until saved. Opportunity to retrieve the annotation only data separately to the image so you can preserve the original.

Currently only Views can be hosted in the MainContent. If users can host Pages the RadSideDrawer could be used as root navigation component. This will allow customers to define the RadSideDrawer once throughout the application.

Applications that are built with AndroidX are currently not supported.

On UWP and Android the item can be swiped beyond the SwipeOffset property. Add option to restrict the swiped distance to the SwipeOffset value.

The purpose of this item is to track demand for support of the MacOS platform in the Telerik Xamarin controls.

Provide support for Interactive Forms (AcroForms) in the PDF Viewer for Xamarin.

My mobile app requires that my data grid have frozen columns on the left that do NOT scroll horizontally.  This is useful when the first column might be an ID column or a Date column that the user always needs to see when scrolling through the other data columns.

Provide and option to apply a shadow.

Add events to handle when listview cells are unloaded/recycled and prepared.

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

Provide a way for Telerik UI for Xamarin controls to look / act same (where applicable) using Material Design.

A PDF Viewer component that you can put in your app will be a great addition to the suite. As a feature set it should at least support pinch and zoom.

Add functionality to slide through the items like in a SlideView/Carousel.

In Xamarin.Forms, there is no multiline text box editor in RadDataForm.

The Source property should support two way binding.

Available in the R2 2018 release.
