Expand TreeViewNode via Code

It would be great to be able to expand nodes dynamically by setting the expand property by code.

protected async Task OnItemClickHandler(TreeViewItemClickEventArgs e)
{
    var item = e.Item as TreeViewItem;
    item.Expanded = true;
}

Duplicated

This item is a duplicate of an already existing item. You can find the original item here:

Hello Florian,

This would be made available through the following enhancement: https://feedback.telerik.com/blazor/1498147-track-changes-in-properties-when-treeview-is-bound-to-observable-collection. I've added your Vote to it and you can click the Follow button there for status updates.

I must note, however, that there is another change coming - a collection of expanded items, so you may want to Follow, Vote (and/or chime in) here: https://feedback.telerik.com/blazor/1448095-expanded-items-handling-feedback-requested.
