In Infragistics 10.2 for Silverlight, what is the prescribed method for determining that a user has performed a double-click on a tree item (node)?  I cannot find something like a MouseLeftDoubleClick event for the XamTree.

I would like to be able to detect and handle a mouse double-click for a node in a Silverlight XamTree.  The idea is to perform a specific action upon a user double-clicking on an item as a shortcut for single-clicking to select the item and then pressing a button.
