Question: How to animate Blur Effect RadiusProperty in C# code?
Notes:
1. I can animate Line position in the same way, but it doesn't work with Blur Effect RadiusProperty.
2. I have XAML code and it works.
3. It must be done on C# code.
4. Duration set to 0 is no problem, it works well with Line position (it happens fast and i see the result immediately).
Code (doesn't work):
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
this.Loaded += MainWindow_Loaded;
}
BlurEffect blur;
void MainWindow_Loaded(object sender, RoutedEventArgs e)
{
Canvas canvas = new Canvas();
canvas.Background = Brushes.Black;
this.Content = canvas;
blur = new BlurEffect();
blur.Radius = 20;
Line line = new Line();
line.Stroke = Brushes.White;
line.X1 = 0;
line.Y1 = 0;
line.X2 = 100;
line.Y2 = 100;
line.Effect = blur;
canvas.Children.Add(line);
Animation();
}
private void Animation()
{
DoubleAnimation da = new DoubleAnimation();
da.To = 0;
da.Duration = TimeSpan.FromSeconds(0);
Storyboard sb = new Storyboard();
Storyboard.SetTarget(da, blur);
Storyboard.SetTargetProperty(da, new PropertyPath(BlurEffect.RadiusProperty));
sb.Children.Add(da);
sb.Begin(); // Doesn't animate.
}
}
