Question

I have a method that enables me to animate objects that have to do with a DoubleAnimation:

public void animDouble(DependencyObject target, DependencyProperty property, double to, TimeSpan duration, double? from = null, TimeSpan? beginTime = null, IEasingFunction e = null)
{

    DoubleAnimation animation = new DoubleAnimation();
    animation.To = to;

    if (beginTime == null)
        beginTime = TimeSpan.FromSeconds(0);

    if (from != null)
        animation.From = from;


    animation.BeginTime = beginTime;
    animation.Duration = duration;


    if (e != null)
        animation.EasingFunction = e;

    //start animating
    Storyboard.SetTarget(animation, target);  // what object will be animated?
    Storyboard.SetTargetProperty(animation, new PropertyPath(property)); // what property will be animated
    Storyboard sb = new Storyboard();
    sb.Children.Add(animation);
    sb.Begin();
}

so if I have a boarder called br1 for example and I want to animate it’s height I will call the method as:

animDouble(br1, FrameworkElement.HeightProperty, 150, TimeSpan.FromSeconds(5));

if I want to animate it’s width I will do:

animDouble(br1, FrameworkElement.WidthProperty, 150, TimeSpan.FromSeconds(5));

I could also animate it’s visibility with the same method.

for some reason I am not able to animate its x property in order to translate it along the x axis or y-axis. When I call the method as:

a.animDouble(br1, TranslateTransform.XProperty, 150, TimeSpan.FromSeconds(5));

the boarder does not animates. I don’t get any errors aether.

Somehow i would have expected an error, well, anyway, the Border owns no such property, if you want to move your control you need to set the RenderTransform or LayoutTransform of the border to a TranslateTransform, then you can pass the transform itself into the method as target.

(The whole storyboard is awfully redundant as you only have one animation, you can just call BeginAnimation on the target itself)
