VB Forum / Enterprise Development / April 2009

I have a tree view, and right clicking on nodes brings up a popup
menu.  Right clicking in empty space brings up a popup menu for the
tree root.  When a root menu pops up, I want to make sure that no node
is highlighted, so that it is clear that the user is working with the
root node.  Right clicking the empty space below the list of nodes
achieves the correct result, but right clicking in the empty space to
the right of a node brings up the root menu, but leaves the node
highlighted.  Commenting out the relevant code, it seems to me that
right clicking the empty space to the right of the node always
highlights the node.  Why is this, and how do I fix it?

Private Sub tvcPartsTree_MouseUp(ByVal Button As Integer, ByVal Shift
As Integer, ByVal X As Long, ByVal Y As Long)

 If Button = acRightButton Then
   pTree.SelectedItem = pTree.HitTest(X, Y)
   If pTree.SelectedItem Is Nothing Then
     DisplayPopupMenu ROOT_MODE
   Else
     DisplayPopupMenu NODE_MODE
   End If
 End If

End Sub

I don't have any code in any other mouse events.
