When i'm using filtering like described in:
I'm not able to tab into the Treeview Control to select an item only with Keyboard Navigation.
The whole TreeView Control is selected (seen on Frame) but i can't select an Item.
If i select one first with the Mouse then i can use Keyboard Navigation.
But i want the user to use only Keyboard Navigation.
This behaviour can be tested with the Demo 'TreeView / FilterSearchSort' in the xaml-sdk.
If i tab through the FilterSearchSort Demo without any Input then i can Stop in the TreeView and Select the First Item with the Space Key.
If i filter the TreeView this doesn't work.
Any Suggestion ?
