adding treeview to visio

[david]

i want to add a treeview to visio.  i saw in insert->control that i can choose "microsoft treeview control".  but the problem is that visio treats the treeview control as one of the shapes on the frame.  if i press ctrl+A for example, visio marks all the shapes on the frame including the treeview.  i want the treeview to be separated.  if it's possible, i want it to be located at the same place the properties are located (in a different tab).

anyone knows how to do that?

thanks in advance
David
