Question

I’ve created some UserControl. Here is its constructor:

public ZoomableChart()
        {
            InitializeComponent();

            this.mainChart = new MainChart();
            this.mainChart.Loaded += new RoutedEventHandler(delegate(object sender, RoutedEventArgs e)
                {
                    this.zoomChart = new ZoomChart();
                });
        }

I don’t want to exit from it until mainChart.Loaded event handler execute. Is there any way to do it?

You can create AutoResetEvent and wait for it.

public ZoomableChart()
    {
        InitializeComponent();
        AutoResetEvent waitLoaded = new AutoResetEvent (false);
        this.mainChart = new MainChart();
        this.mainChart.Loaded += new RoutedEventHandler(delegate(object sender, RoutedEventArgs e)
        {
            this.zoomChart = new ZoomChart();
            waitLoaded.Set ();
        });
        waitLoaded.WaitOne ();
    }
