Hi old friend... I'm back on my HolePatterns WPF project. Man this is fun. I was hoping you'd join in here.

Someone did give me this BeginInvoke solution from the MSDN WPF forum. Yours a little different becuase the delegate is defined inline, and only calls the Focus() method, whereas, I'm actually calling another method, which needs an object references passed in. It does few things, and then sets the focus.

(I'm gonna post the entire project soon, but in the mean time, here is a current screenshot.. http://twitpic.com/1f2ci/full)

Here is my code:

private delegate void focus(HolePattern NewActivePattern);

private void lvHolePatterns_SelectionChanged(object sender, SelectionChangedEventArgs e)
   {
     ListView lvSender = (ListView)sender;
     this.Dispatcher.BeginInvoke(System.Windows.Threading.DispatcherPriority.SystemIdle,
                                           new focus(SetActivePattern), (HolePattern)lvSender.SelectedItem);
   }

and

       private void SetActivePattern(HolePattern NewActivePattern)
       {
               ActivePattern = NewActivePattern;
               HolePatternStackPanel.DataContext = ActivePattern;
               CoordinateGrid1.ItemsSource = NewActivePattern != null ? ActivePattern.HoleList : null;
               RedrawScreen();
               txtPatternName.Focus();
       }
