Vista - WPF MenuItem hiding

Hi,

I would like to hide selected MenuItem on <Delete> key press without closing the menu.

My markup is:


<Menu>

<MenuItem Header="Menu">

<MenuItem Header="First" KeyDown="MenuItem_KeyDown"/>

<MenuItem Header="Second" KeyDown="MenuItem_KeyDown"/>

<MenuItem Header="Third" KeyDown="MenuItem_KeyDown"/>

</MenuItem>

</Menu>

where event handler is:

private void MenuItem_KeyDown(object sender, KeyEventArgs e)

{

if (e.Key == Key.Delete)

{

MenuItem mi = (MenuItem)sender;

mi.Visibility = Visibility.Collapsed;

}

}



Unfortunately, I can not hide currently highlighted MenuItem without the whole menu collapse.



The question is how to bypass this misbehavior? How to change menu selection before hiding?





P.S. Which newsgroup should use I to ask WPF related questions?





Thanks,

-- Dmitry
