Hello Reden,

Please find attached a sample project that demonstrates how to accomplish your goals.

All you need to do in order to have correctly working TreeView with scrolls is just to add something like this:

private void Button_Click(object sender, RoutedEventArgs e)
        {
            RadTreeViewItem item1 = new RadTreeViewItem();
            item1.Header = "item1";
            this.treeView.Items.Add(item1);
            item1.IsSelected = true;
            item1.IsExpanded = true;
            Dispatcher.BeginInvoke(() =>
            {
                item1.BringIntoView();
            });
        }

I hope that this answers your question.

All the best,

Hi Boryana,

Thanks for the quick reply. The solution you've provided works up to a certain extent. When adding a new treeview item on a treeview with 1 level of item, it works fine. The scenario I'm working on is on a 5 level treeview, where I'm adding a new child treeview item in the middle of the tree. For example, the new child treeview item is for the 2nd level, where the 2nd level has more child items that users should scroll the scroll bar all the way to the last child item just to view them. In this example, the BringIntoView fails from scrolling the vertical scrollbar all the way to the viewable level of the new child item (in this case, the last item in the 2nd level).

Thanks again,
Reden
