  I'm not fimiliar with the infragistics treeview control, however the VS version has a selectednode method that retrieves a reference to the currently selected node on the tree....it also has an event "afterselect" in which the event arguments contains a reference to the selected node..

  The Infragistics controls are all extensions of the base controls for the most part so they have pretty much all of the same properties and methods. 

  The reason you're getting the error is you are declaring rNode but you're not setting to anything before you try to change a property.  Try something like this, get rid of rNode altogether:

  if e.KeyCode = Keys.Enter And sender.ActiveNode IsNot Nothing Then
     sender.ActiveNode.CheckedState = CheckState.Checked
  End If
