is just a view
over the original collection. This means that if you define a filter in the QueryableCollectionView
, it will represent the filtered version of the original collection. So in your case you can set the items
collection as the ItemsSource
of the RadTreeView. This way it will display the filtered collection. However, as soon as you change the value of the IsVisible
property of any item, you'll need to refresh the QueryableCollectionView
to reflect the changes and to create a new view of the original collection based on the new settings of the IsVisible
property. I attached a sample solution demonstrating this approach.
You can also have a look at this demo solution
demonstrating how to filter, sort or search through the RadTreeView ItemsSource
Let me know if that info helps or if I can further assist you.
