Binding Observable Collection to multiple wpf trees

Question

Does anyone have suggestions on the best way to bind an observable collection to multiple wpf trees using different groupings? Both bindings are two-way, such that changes in one control should be reflected in both controls.

Answer 1

I was able to modify this sample ( http://blogs.msdn.com/b/mikehillberg/archive/2006/10/11/a-treeview-a-hierarchicaldatatemplate-and-a-2d-collection-walk-into-a-bar.aspx ) by adding a secondary grouping and an additional tree. Grouping by different fields worked well.

I then added a button to add an item with round-robin groupings to the collection and a little snippet to find and select the items in both trees ( social.msdn.microsoft.com/forums/en-US/wpf/thread/7e368b93-f509-4cd6-88e7-561e8d3246ae ), and it all works well.

I am still curious to know alternatives.
