Hi Adrian Pay,
Basically there are two approaches you can take to achieve this functionality. First, you can go in Expression Blend, edit the ControlTemplate of RadTabControl and remove (or hide) the header strip. The other way is to collapse it using the VisualTreeHelper class like this:
var root = VisualTreeHelper.GetChild(
var headerElement = root.FindName(
headerElement.Visibility = System.Windows.Visibility.Collapsed;
I'm sorry for the inconvenience and hope the answer will be of help to you. Let us know if you have further questions.
