I now have a treelist with a few thousand items, but the filtering takes a few seconds, and halfway there is a refresh with partial results.

Now the users are complaining that they do not really know when the treelist is done with filtering.

I have a TreeList, bound to an ObservableCollection data source. When I try to add new children the component stays in Create mode even after I click on the Update button.

I would like to start the tree grid with all rows collapsed. At the moment I can do this only through load on demand.

I would like the TreeList to support row virtualization. It will be useful when working with large data.
