Force redraw before long running operations

by

The following code will do what you’re looking for. However I would not use it. Use the BackgroundWorker class for long time operations. It’s easy to use and very stable.
Here the code:

   public static void ProcessUITasks() {            
        DispatcherFrame frame = new DispatcherFrame();
        Dispatcher.CurrentDispatcher.BeginInvoke(DispatcherPriority.Background, new DispatcherOperationCallback(delegate(object parameter) {
            frame.Continue = false;
            return null;
        }), null);
        Dispatcher.PushFrame(frame);
    }

Here you will find a sample on how to use the BackgroundWorker.
