I got it to display by removing SelectedValuePath="Id"
The issue I'm having now is when you select items, the empty text will still be there. If you click in between the items, there's a small spot, it closes the dropdown and the empty text disappears and is now filled with the selected items text. If I then unselect all the items, it's empty, probably still displaying ItemsSource.SelectedItemsText.
If I remove the selectedItemsText, doing the same thing puts the last click item in the box. Perhaps this is a telerik / wpf bug?
Thank you for the provided code snippets and sample picture.
Can you share whether you are using multiple selection by setting the AllowMultipleSelection property of the RadComboBox to True? If that is the case, you should utilize its MultipleSelectionBoxTemplate property.
That said, I am uncertain what causes the behavior described in your last reply. That is why I attached a sample project I created trying to reproduce the scenario. May I ask you to modify it in order to demonstrate the behavior and send it back? You can open a new support ticket and attach it there, since such files cannot be attached to a forum post. This way I will be able to investigate the scenario and better assist you.
Thank you in advance for any help you can provide.
