Silverlight 3 MouseLeave Event Controlling PopUp

I want to use the PopUp control (System.Windows.Controls.Primitives.PopUp) to display a context menu. After the leaves, the mice should be automatically closed. But the event handler for MouseLeave never gets executed. Why?

SAMPLE:

void DocumentLibrary_Loaded(object sender, RoutedEventArgs e)
{
    DocumentLibraryDialog documentLibraryDialog = new DocumentLibraryDialog();

    _popUpDocumentLibraryDialog = new Popup();
    _popUpDocumentLibraryDialog.Width = 70;
    _popUpDocumentLibraryDialog.Height = 20;
    _popUpDocumentLibraryDialog.MouseLeave += new MouseEventHandler(_popUpDocumentLibraryDialog_MouseLeave);
    _popUpDocumentLibraryDialog.Child = documentLibraryDialog; 
}

void _popUpDocumentLibraryDialog_MouseLeave(object sender, MouseEventArgs e)
{
    Popup currentPopUp = (Popup)sender;
    if (currentPopUp.IsOpen)
        (currentPopUp.IsOpen) = false;
}

Hello

What type of child controls are in the popup? In other cases with WPF / Silverlight, I have child controls that swallow messages that would be good for the parent.



As an experiment, what happens if you attach MouseLeave handlers for child controls?

you need to bind the event in Popup.Child instead of the popup itself, it might be a Silverlight bug.
