I have a program where I have a GridTree bound to a viewmodel. When I update the contents of the view model the changes are not being reflected back into the tree until I select a different node on the tree.
I have tried all of the following but none seem to work;
- For the TreeGrid I have set the UpdateMode to the various different setting, none seem to have any effect
- When the viewmodel is updated I trigger a "PropertyChanged" event on the collection that the GridTree is bound to - this also has no effect.
The changes that should be displayed in the tree are in the "columns" of the gridtree, do I need to do anything to get these updated?
