We have one xaml file with TabControl and a seperate xaml file for each TabItem (see example below). We add the TabItems dynamically in code. This works fine for TabControl and TabItem: both the image and the text show in the header of each TabItem. When we switch to RadTabControl and RadTabItem, the first RadTabItem we add doesn't show its header: we don't see the image or the text. The second RadTabItem we add does show both the image and text as we were expecting. Could you look into this?
<TextBlock Text="Adressen" />
