Blinking animation WPF

Question

I have this animation with me, a sort of blinking animation, such that when the button is clicked, the rectangle \"blinks\". I\'ve written a code for the animation, just wanted

Answer 1

Here is C# code version for someone who need it...

    if (IsImageBlinking)
    {
        DoubleAnimation da = new DoubleAnimation();

        da.From = 1.0;
        da.To = 0.0;
        da.RepeatBehavior = RepeatBehavior.Forever;
        da.AutoReverse = true;

        sb.Children.Add(da);
        Storyboard.SetTargetProperty(da, new PropertyPath("(Image.Opacity)"));
        Storyboard.SetTarget(da, image1);
        sb.Begin();
    }

From other hand there you can implement blinking for any control like this.

 
        0 5 0 0
        
            
        
        
            
        
    

AlertArea is to generate blinking 3 times and when it is finished we have to restore Opacity using AlertArea2.

In the constructor of UserControl/Window

..
Storyboard sb = this.FindResource("AlertArea") as Storyboard;
sb.Completed += Sb_Completed;
..

private void Sb_Completed(object sender, EventArgs e)
{
    Storyboard sb2 = this.FindResource("AlertArea2") as Storyboard;
    sb2.Begin();
}

In the place you need to start blinking do this

Dispatcher.BeginInvoke((Action)(() =>
{
    Storyboard sb = this.FindResource("AlertArea") as Storyboard;
    sb.Begin();
}));
