I am using the RadDiagramThumbnail to show a thumbnail overview of the diagram, how it is implemented is very much like the example in the documentation for the DiagramNavigationPane (i.e. not a complicated or custom implementation). Associated with the diagram is a treeview control by which the user can show/hide nodes by checking/unchecking in the tree (again, not too complicated I just have a node view model property bound to each node's Visibility property). But I have noticed the following behavior with the RadDiagramThumbnail pane:
If the thumbnail/navigation pane is open and the user moves a node in the diagram, the thumbnail will update, but if the user change's a nodes visibility (e.g. collapses one or more nodes), then the thumbnail does not update. If nodes in the diagram are moved after a visibility change, then the thumbnail will update accordingly.
How do I enable the thumbnail view to update when a node's visibility has been changed?
Thanks,
Mike
