title: How to cancel node selection in nodemouseclick event
body: <p>Is there a way to cancel the selection of a new node inside a <code>NodeMouseClick</code> event? (By "cancel", I mean have the selection revert to the previously selected node.)</p>
  
  <p>This was easy in WPF by handling the <code>e.handled</code> boolean variable. In Winforms there's no such thing so I really don't know how I should handle this problem.</p>
