Canceling tab selection

[yanairon]

Hi, does anybody knows what is the WPF way to avoid Tab Selection? in WinForms i had the Selecting event which i could cancel (with CancelEventArgs) i need to cancel (or not) based on the tab which i"m exiting (the previous tab). i get all that information in SelectionChanged but that's too late to cancel. i can't use MouseClick because i don't have all the information i need. all i've managed is the following (ugly) code in SelectionChanged:

    if (!m\_InSelectionChanged && e.Source == e.OriginalSource)
        {
            m\_InSelectionChanged = true;
            if (e.RemovedItems.Count > 0)
            {
                TabItem unselecetd = e.RemovedItems\[0\] as TabItem;
                TabItem selected = e.AddedItems\[0\] as TabItem;

                if (selected != null && unselecetd != null)
                {
                    CancelEventArgs args = new CancelEventArgs();
                    Check(args);
                    if (!args.Cancel)
                    {
                         // Logic    
                    }
                    else
                    {
                        // Re select what was previously selected
                        m\_TabControl.SelectedItem = unselecetd;
                    }
                }
            }
            m\_InSelectionChanged = false;
        }

any other ideas? no way that it can't be done in wpf with some technique yanai
