Vista - BindingContext like in System.Data

Hi,

I try to understand WPF databinding.

I have a custom component for WinForms applications that abstracts
DataBinding issues in WinForms.

To get notified when the UI changes a DataView (I bind to) (ComboBox
chnanges item) I use the BindingContext of my form in my component. This
works, of course.

Now, in WPF I see that there is no BindingContext anymore.

My question:
Is it possible to get notifed when the UI changes an Item outside my Window,
is there something like BindingContext?

I see there is a ItemChanged event in BindingListCollectionView but I want
to bind against System.Data.DataView.

Thanks,
Christian
