Hi,
i add some Messages to a RadListBox in codebehind, using a Backgroundworker. If i start my application all ist fine.
But if i cklick on a button which starts the void again, i get all messages twice.
How can ein clear or remove all the items of my RadListBox before i start again?
radlistbos.Items.Clear(); - does not work
Or is there a way to clear the Backgroundworker ReportProgress?
Thanks a lot
Best Regards
Rene

Hi Rene,
In order to clear the Items from the RadListBox we can clear the ViewModel's collection that the RadListBox.ItemsSource is bound to. I've attached a sample project demonstrating this approach.
If the proposed way is not suitable for your scenario or it does not resolve the issue I would like to ask you for a project or code sample that demonstrates the problem in order for us to investigate and help you further.
