I want whenever an item is added for it to start expanded.
My treeview is bound to a viewmodel.
I am using code examples from the forums to bind the isexpanded to a viewmodel isexpanded property like below.
The code worked for a bit and then recently stopped . the treeview does not render at all if the style is applied. if I remove the style it works fine.
Any ideas. is there a simpler way to do it .
Any help would be appreciated.
