Update header from code behind, when tab is dragged out

[BornToBeRoot]

Hi,

i try to update the header text from the code behind. I have an action, which is passed into the tab content.

In the tab control host:

public ObservableCollection<DragablzPingTabItem> TabItems { get; private set; }
Action<Tuple<int, string>> ChangeTabTitleAction;

private void ChangeTabTitle(Tuple<int, string> obj)
{
    TabItems.First(x => x.ID == obj.Item1).Header = obj.Item2;
}

In the control:

ChangeTabTitle.BeginInvoke(Tuple.Create(_tabId, Host), null, null);

But this only works, when the tab is not dragged out of the main window.

Any idea how to fix this?

This may not be nice, but at least it works...

Window window = Application.Current.Windows.OfType<Window>().FirstOrDefault(x => x.IsActive);

if (window != null)
{
    foreach (TabablzControl tabablzControl in VisualTreeHelper.FindVisualChildren<TabablzControl>(window))
    {
        tabablzControl.Items.OfType<DragablzPingTabItem>().First(x => x.ID == _tabId).Header = Host;
    }
}
