I will go straight to your questions:
In general, RadTreeView does not provide the conception for selection (selected item, selected index, etc). I would suggest you enable CheckBoxes support
instead in order to highlight certain items and implement some logic on them. Basically, we've designed the control in a way it is suitable for using on a mobile device.
a) I didn't manage to reproduce this behavior, can you send me the ListView definition, so I could research it further?
b) I am afraid that the manipulation logic for swipe, tap and other is implemented on RadListViewItem and is internal, so basically it cannot be overridden. The swipe is invoked through mouse down and mouse move actions.
As to the last question about double-click - could you elaborate more on this? Some sample code would be of great help as well.
I am looking forward to your reply.
Do you want to have your say when we set our development plans?
Do you want to know when a feature you care about is added or when a bug fixed?
