TreeViewItem selection not removed when selecting another item

[gautambjain]

I was able to programmatically select an item using one of the below methods:

1. TreeView.SelectedItem = model;
2. TreeView.SelectedNode = node;
3. TreeViewItem.IsSelected = true

All of these work. But when selecting any other item using mouse does not remove the selection done through the above method.

So, always, I have 2 items selected. The one selected programmatically. Another selected using mouse.

Am I missing something or is it a bug?

Answering my own question. It wasn't working in the "Drop" event handler. Not sure why. But it worked in RightTapped event. Thanks.
