Clear filters from viewmodel?

[LoyalServant]

If I have a datagrid with an ItemsSource bound to an ObservableCollection, and that ObservableCollection changes, how do I clear the existing filters?
In my case I am clearing the collection, and adding new items so the existing filter is in place and working, but it no longer applies. This means the user has to manually remove it - if they realise that's why they are not seeing what they expect to see.

Thoughts?
Thanks all.

Hard to say without seeing the sources.

Can you add your use case to the sample app and provide a PR?
