Hello
Vijayalakshmi,
thanks for your answer.
Yes, in the video this is the point where I am. I add a Item and I must rightclick, navigation-option and change the value. But I search a way to add this directly without that I must use rightclick, menu... or where or what is the property to change this value in c#? In documentation I found in the WinForm - Groupbar the property IndexOfVisibleItems (or so), but not for the WPF-Control.
I will add the items with a RegionManager, so that when a module will loaded the item is automatically will shown.
Thanks you.
Regards Ronny
