I have a grid, a window root element. I want to apply an animation which would change it's background color from white to green in 5 seconds. Here's what I did:
private void Window_Loaded(object sender, RoutedEventArgs e)
{
ColorAnimation animation;
animation = new ColorAnimation();
animation.From = Colors.White;
animation.To = Colors.Green;
animation.Duration = new Duration(TimeSpan.FromSeconds(5));
rootElement.BeginAnimation(Grid.BackgroundProperty, animation);
}
The code doesn't work. Nothing is changing. Where am I making a mistake? Thanks.
Solved!
private void Window_Loaded(object sender, RoutedEventArgs e)
{
SolidColorBrush rootElementBrush;
ColorAnimation animation;
rootElementBrush = this.FindResource("RootElementBrush") as SolidColorBrush;
// Animate the brush
animation = new ColorAnimation();
animation.To = Colors.Green;
animation.Duration = new Duration(TimeSpan.FromSeconds(5));
rootElementBrush.BeginAnimation(SolidColorBrush.ColorProperty, animation);
}
Here's an explanation:
My initial mistake was that I wanted to change the Grid.BackgroundProperty
by assigning colors to it, but it accepts brushes instead... apples and oranges! So, I created a SolidColorBrush
static resource and named it rootElementBrush. In XAML, I set Grid rootElement
's background property to that static resource. And finally, I modified the animation, so now it changes the color for that SolidColorBrush
. Easy!
