Hi,
Due to our project requirement, we are implementing RadTreeListView CTP control, and replacing with RadTreeView. In RadTreeView, we are able to add binding in sorted order through CollectionViewSource. As we implemented this new CTP control, we are not getting any result. Please suggest..

CollectionViewSource svc = new CollectionViewSource();
svc.SortDescriptions.Add(
new System.ComponentModel.SortDescription("Name", System.ComponentModel.ListSortDirection.Ascending));
svc.Source = <here we have observablecollection>
tvDocuments.DataContext = svc;
But end result is nothing. The problem is when we get new item in collection, it is adding in bottom of tree and we want to make it sort.
I will apprecicate your response.
Thanks,

Hi kapil goyal,
I am sorry for the delayed reply.
Please note that the TreeListView is a CTP and major changes are expected for its next version as we are going to base it on the RadGridView. It is best not to base any production code on it yet.
I checked that the TreeList does not show the sorted items as expected. The ItemsSource needs to be reset to show the updated this. The release version of the TreeList will work with CollectionViewSources and will have a built-in support for sorting (like the GridView does now).
You can have a look at the attached project.
