Same here!  Especially considering this bug only exists in the Telerik control, it works fine in the standard WPF listbox.

Hi,

In order to workaround this issue you could use the SelectionHelper of the RadListBox control and set its SelectItems collection directly. The next code snippet shows the described workaround:

- the XAML declaration:

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
...
<telerik:RadListBox x:Name="radListBox" 
                    ItemsSource="{Binding Items}" 
                    DisplayMemberPath="Name" ></telerik:RadListBox>

- and in the code behind when setting the SelectedItem:

var items = (this.DataContext as ViewModel).Items.OfType<Item>().ToList();
this.radListBox.SelectionHelper.SelectItems(new List<Item> { items[0] });

Can we get this fixed? It's been more than one and a half years since the feedback item was submitted and the suggested workaround does not work in an MVVM implementation.

I see this is now 'Completed'. Great! What version will the fix be in?

I just tested using version 2015.1.601 and still experience the bug. Please see my related support ticket with ID 901043. It contains a sample solution that demonstrates that the bug still exists.
