I've been using WPF for a while now and I've gotten pretty used to many of the (rather daunting to the uninitiated) features: XAML, Binding, Templates, Triggers, etc. But I just can't seem to fully grasp the event system. Something that has gotten on my nerves from the very beginning is that events that are called 'changed' events (ie ...

I would like to synchronize two object headers with pointers. For example: I know I can't do this with the current syntax, but I would like something like: Node node = new Node(); node.Label = "header1"; TabItem tabItem = new TabItem; *(tabItem.Header) = &(node.Label); So whenever I change node.Label, tabItem.Header changes as well...

I have an ObservableCollection of ChildViewModels with somewhat complex behaviour. When I go to edit a row - the DataGrid goes into 'edit-mode' - this effectively disables UI-notifications outside the current cell until the row is committed - is this intended behaviour and more importantly can it be changed? Example: public class View...
