programmatically select and expand treeviewItem when bound to a collection
I have a treeview which is bound to an observable collection.
After I insert an element in the collection it appears in my treeview.
Since the collection is of base type INotifyPropertyChanged the treeview methods are no longer available.
I want to be able to set "IsSelected" from code behind.
What is the best way to do this?

For Silverlight, as a workaround, you can check this post about SetterValueBindingHelper :

It look like the setter binding is only supported in WPF... And did not mention that I used SL4 in the above question. This method would do what I wanted. I looked at some other posts with work around but they seem very complicated...
Do you have any other sources of help that could tell me how ?
