Question

I am implementing an application, and if I click on a menu item:

 <MenuItem Name="menuAlgemeneGeg" Header="Algemene gegevens" Click="AlgemeneGegevensClick" />

the method is :

private void AlgemeneGegevensClick(object sender, RoutedEventArgs e)
        {
            ToetsBeheerViewModel vm = (ToetsBeheerViewModel)this.DataContext;
            EditAlgemeneGegevens window = new EditAlgemeneGegevens(vm.Examination);
            window.ShowDialog();
            menuAlgemeneGeg.IsEnabled = false;

        }

Now what I want is, that when you click on it the menuitem is disabled. But from the moment the user closes this window it must be enabled again. I can disable the menuitem but can’t change this back to enable it.
Someone who can help me out please?

Answer 1

you can handle window closed event.. and enable menu in even handler

private void AlgemeneGegevensClick(object sender, RoutedEventArgs e)
        {
            ToetsBeheerViewModel vm = (ToetsBeheerViewModel)this.DataContext;
            EditAlgemeneGegevens window = new EditAlgemeneGegevens(vm.Examination);
             window.Closed += new EventHandler(Window_Closed);
            window.ShowDialog();
            menuAlgemeneGeg.IsEnabled = false;

        }

 void Window_Closed(object sender, EventArgs e)
        {
             menuAlgemeneGeg.IsEnabled = true;
        }
