Scrolling to selected item in TreeListView

[Kate]

Hello! I have scenario when I have to add items to the collection that is bound to the RadTreeListView's ItemsSource property in code. When I add items I change the SelectedItem property that is bound to SelectedItem property of RadTreeListViewSource (the binding mode is set to TwoWay). New item becomes selected, but the RadTreeListView doesn't scroll to it. How can I scroll to the item, that was added? If I use ScrollToView metod of the RadTreeListView I sometimes get an Exception in GridViewVirtualizingPanel.MeasureOverride(size).

Hello Kate,

Please try with the ScrollIntoViewAsync method. In this forum thread you can find a sample project.

I've already studied the Scrolling example. And I've also used the ScrollIntoViewAsync method. The result was the same. I've noticed that the error occured when I resized the RadWindow which contained my RadTreeListView before a new item was added. The problem can be solved by setting EnableColumnVirtualization and EnableRowVirtualization properties to false. Is it my or RadTreeListView's mistake?

Thanks for your reply!

I have another problem with ScrollIntoView and ScrollIntoViewAsync methods in the RadTreeListView. They scroll my rows to the bottom of the scroll area and show just the top of it (my control in the row of RadTreeListView has height="auto").How can I scroll the whole control?

Hi Kate,

I would ask you to send us a sample project in a new support ticket so we can have a better look on what is going on.
