By default, displaying the context menu associated with a WPF TreeView node does not affect which nodes are selected. In my TreeView, I would like for the node associated with a displayed context menu to become the selected node.
I have researched similar questions that have been answered here, including this one, this one, and this one. To my surprise, none of the answers provided are satisfactory because they all presume that a right mouse click is the event that causes the context menu to be displayed.
While a right mouse click has long been a standard method of displaying a context menu, it is not the only way. For example, the user might use the "menu" key on the keyboard. New input devices, and new ways to display context menus might emerge in the future. Approaching this problem by attempting to anticipate all of the different things that could cause a context menu to be displayed seems wrong.
Is there a solution to this problem that is agnostic to the specific input device(s) in play?
The solution I arrived at is similar to what @emoacht proposed, but handles the ContextMenuOpening event on the context menu's parent control, instead of the OnOpened event on the context menu itself. This way, the node selection and context menu display occur in the desired sequence.
