when changing property value programmatically, the row background style selector does not apply. You need to scroll the data or resize the control, then the change applies.
The selector works when editing the datagrid value trough the UI, but does not work when changing the value programmatically.
When the numerical column enters edit mode, in order to display the keyboard you need to tap one more time.
Outside of the datagrid, when the numeric input control gets focused, the keyboard appears.
Keyboard navigation to editable cells does not retain text selection. Having the SelectionOnFocus to “SelectAll” and the cell is in edit mode, the text gets selected
pressing enter or tab key, the text in the next cell is not selected.
I have tried implicit style, cell edit templates, same result, text gets deselected.
We've got a CollectionView which shows a list of grouped items (grouping can be by date or other values - but date is the default).
The CollectionView items source is bound to an observable collection, and when the viewmodel saw an item removed from the observable collection, the Telerik control crashed. We've seen instances of this app crash on Android (the same control hasn't been released to other platforms yet). We do not have reproduction steps as this is a rare issue, but it feels like it is worth communicating as you might be able to spot what is going on from your end.

any ideas on what might be going on here?
