Animations with storyboards in WPF are cool, but often we need to be able to trigger them to start from cs codebehind. For example, on a button click. Here the animationKey param is the key that is defined in the xaml for your storyboard.

private void StartAnimation(string animationKey)
{
     Storyboard pageViewAnimation = (Storyboard)FindResource(animationKey);
     pageViewAnimation.Begin();
}

Setting the Image.Source property in WPF. Note this is slightly different than in silverlight because it requires an object holding the image data as source.

private void SetPageViewImage(string sourceFile)
{
	Uri uri = new Uri(sourceFile, UriKind.Relative);
	ImageSource imgSource = new BitmapImage(uri);
	PageViewImage.Source = imgSource;
	PageViewImage.Visibility = Visibility.Visible; //optional
}
