Hi Balaram Barange,
Can you please find the attached example. Even when the RadTreeView is loosing the focus pressing the Esc
still works and the dragging is Canceled for both examples with RadTreeView and ListBox.
The FocusLost is raised in the meantime of changing the selected item (the TreeView just gets the focus after the current selected item loses it and after that the newly selected gets the focus, so the TreeView loses it) . The only focused visual element in the focus scope is RadTreeViewItem (the selected one), that's why the TreeView iteself can't be focused too.
Can you please reproduce your problem and send us back the example, so we can examine it?
