How to get the corresponding RadTreeViewItem of a BusinessObject?

[Julien]

Hi!

I'm adding from the code an object to one of my recursive ObservableCollection. There is a root ObservableCollection that is set as ItemsSource. 

When I add it to my collection, I want to select it on my tree.

So how can do this? I cannot find any methods that permits me to get a RadTreeViewItem of my added object.

I've seen that: http://www.telerik.com/help/wpf/radtreeview-how-to-get-item-by-path.html but I'm not sure there will never two element with the same displayed name

Hi Julien,

You can subscribe for the ItemPrepared event of RadTreeView and select the newly added item there:

void treeView1_ItemPrepared(object sender, Telerik.Windows.Controls.RadTreeViewItemPreparedEventArgs e)
{
    // e.PreparedItem is the RadTreeViewItem container of the newly added item
    e.PreparedItem.IsSelected = true;
}

I've added a sample project demonstrating this scenario. Let me know if this works for you.

Is there something corresponding for GridList?

Hello Julien,

You can simply add the newly added item to the SelectedItems collection of the grid.
