How to redraw (update) a diagram

Hello everybody!

I have a diagram with nodes and additional text in them. And I need show and hide this additional text by push the button. How can I update diagram or redraw it? Can I redraw all nodes manually by calling DrawNode function, or Diagram class has some method to update it?
If someone knows how to do it, please help me

Hi!

Call node's Repaint method if you need to run custom-draw event handler. Repaint calls InvalidateVisual and WPF redraws the node asynchronously in a while.
