Error while adding to RadPane as IsPinned = false

[Michael]

When add a RadPane to a RadPane group as IsPinned = false, I get the following error.

public MainWindow(){
InitializeComponent();
RadPane rp = new RadePane();
rp.CanUserClose = false;
rp.CanFloat = false;
rp.CanUserPin = false;
rp.CanDockInDocumentHost = false;
rp.IsSelected = false;
rp.IsPinned = false;
rpgRight.Items.Add(rp);
}

Hi Michael,

We've created a project with the details you've sent us, but we didn't manage to reproduce the issue. As we can see from your request, it is a WPF project and you are using latest dlls (2012.3 1017).

Please, take a look at  the attached sample to check did we miss something important.

We would like to have more information to be able to investigate the issue.

All the best, Alek
the Telerik team
