Programatically Adding Controls

Question

I have a class which adds items to a WPF Stackpanel however this does not seem to work instantantly it is working after i have restarted a timer on my page.

Does this need some sort of event to refresh the WPF page and instantly make the changes take effect.

Code: Ellipse myEllipse = new Ellipse(); SolidColorBrush mySolidColorBrush = new SolidColorBrush(); mySolidColorBrush.Color = item.BallColour;

        SolidColorBrush myBackGroundTransparent = new SolidColorBrush();
        myBackGroundTransparent.Color = Colors.Transparent;

        StackPanel myStackPanel = new StackPanel();

        myEllipse.Fill = mySolidColorBrush;
        myEllipse.StrokeThickness = 2;
        myEllipse.Stroke = Brushes.Black;
        myEllipse.Width = 50;
        myEllipse.Height = 50;
        myEllipse.Margin = new Thickness(10, 0, 20, 0);


        Label myLabel = new Label();
        ResourceDictionary res = (ResourceDictionary)Application
                     .LoadComponent(new Uri("../Styles/Styles.xaml", UriKind.Relative));
        Style style = (Style)res["LittleBallLabel"];
        myLabel.Style = style;
        myLabel.Content = item.Number;


        myEllipse.Tag = myLabel;
        CalledNumber1.Children.Add(myEllipse);
        theNumber.Children.Add(myLabel);
