OK, so I need to create an ICollectionView
from an existing ICollectionView
.
The idea is that I can take whatever filters/grouping/sorting has been set on the existing view and then create other views from that "base" view, in effect "layering" or aggregating my filters, etc.
I need the end view to update its items "auto-magically" when the source collection (an ObservableCollection<T>
) updates and when the data item is updated--like calling the Refresh()
method. I need to avoid calling Refresh on all the views because we don't know all the views between the original collection and the end view, and the Refresh()
is painfully slow.
We are trying to avoid rolling our own view classes--we would prefer (strongly) to use something that already exists in the .net library.
Update
We have a call in to Microsoft about this. I know others have the same problem, as least, that what Dr. WPF tells me.
