Hello,
I am building a tree programmatically. After adding all of the items i would like to select one of them and to scroll to it (ensure that it is visible). i am using the node object (RadTreeViewItem) to set the IsSelected property to true, and then use the EnsureVisible method. The node is indeed selected. However any methods that are registered to the Selected event are not invoked. In addition, the item stays invisible and manual scrolling is required.
Any ideas?
thanks,
Liat.

Hi Liat,
About selecting and showing the item please preview the Expanding a Databound TreeView initially article. There is a working example too.
About the selected event please note if the container is not constructed then the Selected event is not raised. Instead you can rely on the SelectionChanged event of the TreeView control.
Sincerely yours,

Hello Jean-Marc,
This is an old thread and the link and the approach it described, don't work anymore. Instead, you can have a look at this blog post describing the RadTreeView.BringPathIntoView method. If you need to bring virtualized items into view, this method is your best choice. As the solution attached in the blog is targeting Silverlight, I've attached its WPF version here.
All the best,

I wish to thank you for the code you sent me, I found a solution to that works fine with the IEventAggregator.
