MouseLeftButtonDown error?

[David Walton]

Hi!

I've got a RadTreeView and I don't seem to be able to capture a MouseLeftButtonDown event.  Left clicks & double-clicks work as expected expanding & collapsing the tree branches.  Also, left click selects and drag & drop work as expected.

I'm trying to hack the treeview to expand/collapse on a right click and perform some custom behavior on double-click.  I've disabled single-click and double-click expand/collapse (which inhibits that behavior appropriately), however no amount of left-clicking or double-clicking fires the MouseLeftButtonDown event.

Any thoughts?

Thanks!

Hello David,

Yes, indeed we handle the MouseLeftButtonDown event in the TreeView.

If you want to handle handled events, you can register for them using the AddHandler method:

someElement.AddHandler(FrameworkElement.MouseLeftButtonDownEvent, OnMLBF, true);

This overload of the method (with true) will handle handled events.

Sincerely yours,
