Currently, if the value contains longer text, the barcode is not expanding, just uses smaller points to accommodate it. 

In addition, the barcode does not take all the available space (with Stretch Sizing mode).

Provide an easy way to position the popup in the center of the screen in a MVVM-friendly manner. 

Consider the case when the target is a view that carries information about the popup and cannot be the page.

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

Request

Android follows a "bottom-up" approach to gesture/touch handling. It would be nice if the RadSlideView would allow any swipe gesture that it cannot handle itself to propagate upwards so that another view can have a chance to handle it.

Example

Given the following XAML:

<ParentView>
        <ParentView.GestureRecognizers>
            <SwipeGestureRecognizer Direction="Left"
                                    Command="{Binding ForwardCommand}" />
            <SwipeGestureRecognizer Direction="Right"
                                    Command="{Binding BackwardCommand}" />
        </ParentView.GestureRecognizers>

        <RadSlideView />
</ParentView>

Expectation:

• When the user is at the beginning of the items in the RadSlideView and swipes right, then the BackwardCommand should execute. (The RadSlideView should detect that it is at the beginning of its item source and allow the right swipe gesture to propagate upwards to the ParentView.)
• When the user is at the end of the items in the RadSlideView and swipes left, then the ForwardCommand should execute. (The RadSlideView should detect that it is at the end of its item source and allow the left swipe gesture to propagate upwards to the ParentView.)

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.

It would be handy to enable dates/disable dates based on an array of dates. 

I have a situation where drivers are scheduled jobs that may exclude days within a 3-week period.  Currently I can only select set the minimum and maximum dates for this period which allows them to select dates where no work is scheduled.  Consequently my code must check if the selected date "is valid" before allowing displaying the jobs for the selected date.

Obviously it would be far easier if those dates were never enabled in the first place.

Capability to automatically detect the at symbol "@" for mentions (maybe against a collection of 'contacts') and the ability to detect the pound symbol '#' for hashtag creation.

Currently in 2019 R2 and earlier, the "options" button at the bottom of the filtering UI allows the user to rearrange and toggle the visibility of columns in the DataGrid.

I request to have a property or setting on the DataGrid or the DataGridColumn that will prevent the user from changing the visibility or ordering of columns. from that UI (just like you can prevent user filtering or user sorting)

Currently, the only way to set the TextColor for the RadNumericInput is to extract the ControlTemplate and set the TextColor of the internal NumericInputEntry component.

A simple and quick fix is to add a TextColor BindableProperty to the RadNumericInput control and use a TemplateBinding on the NumericInputEntry style

Currently, there is no ItemTemplate for the SegmentedControl, therefore we need to use an IEnumerable<string>.

Please add support for ItemTemplate, or DisplayMemeberBinding property, so that we can bind to an IEnumerable<T>.

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..
