Request for RadioButton-like mutual exclusive selection using a Group type of property.

Ex:

<CheckBox Group="Gender" />
<CheckBox Group="Gender" />
<CheckBox Group="Gender" />

When one of the CheckBoxes in the Gender group are checked, any other selections are cleared.

It would be nice if we can just bind a .net DataTable or DateView as ItemsSource to the RadDataGrid.

As an effect of this, characters, which are not contained in the StandardEncoding names, e.g. umlauts, are measured with incorrect glyph widths. This leads to incorrect glyph positioning in RadPdfViewer.

Currently if the TreeView has deeper hierarchy or items with longer text, the end user will not be able to scroll horizontally.

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

I just want to know, whether the image is changed or not.

- The user opens the image with the Image-Editor.

- The user closes the Image-Editor. If the Image was changed, I want to save the image automatically

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.

Add controls to selecting dates/times that also support null or blank values.  Currently the DatePicker control that is provided as part of Xamarin Forms doesn't allow for a null or blank date.
Provide the ability to select date and time in single UI.

Add public-facing methods to re-call DataSourceProvider GetSourceFor methods. This would allow for refreshing the datasource.

Alternatively, add support for ObservableCollection to be used for DataSources so that the pickers reflect any changes to the underlying data source.

I have come across some strange behaviour of the RadSideDrawer component. On Android, everything works fine. On iOS however, the side drawer opens only when navigated to the containing page for the first time. when we have a button inside the drawer content and navigate through it to another page, then back to page where sidedrawer is positioned, the drawer content could not be open.
