Hi,

In my application I have a DockManager that contains the following piece of code:

Now I want to use data binding to occupy the TabGroupPane with instances of UserControls.

So in my C# code I have an ObservableCollection (DocumentsList) that contains UserControls.

Now I want to bind this collection to the ItemsSource of TabGroupPane.

I do this by using the following code:

This code works and when I add multiple UserControls to the ObservableCollection they are being shown:

But when I am trying to use a document (like switching between the documents) it won't work and ik get errors (Operation is not valid while ItemsSource is in use. Access and modify elements with ItemsControl.ItemsSource instead.)

Am I doing something wrong or is it just not possible?!

Kind Regards,

Arjan
