Compile error while animating on Windows Phone
I am new to Windows Phone animation and am using the below code but it gives me compile error:
'System.Windows.Controls.Button' does not contain a definition for "BeginAnimation" and does not use the "BeginAnimation" extension method taking a first argument of type "System.Windows.Controls.Button" (are you missing a directive or assembly reference usage?)
Which link am I missing?

da.To = 100;
da.Duration = new Duration(TimeSpan.FromSeconds(1));
button1.BeginAnimation(Button.HeightProperty, da);
}

The UIElement.BeginAnimation method does not exist in WP7. Instead, you will need to create a storyboard like this:
private void button1_Click(object sender, RoutedEventArgs e)
{
var sb = new Storyboard();
var db = CreateDoubleAnimation(30, 100,
button1, Button.HeightProperty, TimeSpan.FromMilliseconds(1000));
sb.Children.Add(db);
sb.Begin();
}
private static DoubleAnimation CreateDoubleAnimation(double from, double to,
DependencyObject target, object propertyPath, TimeSpan duration)
{
var db = new DoubleAnimation();
db.To = to;
db.From = from;
db.Duration = duration;
Storyboard.SetTarget(db, target);
Storyboard.SetTargetProperty(db, new PropertyPath(propertyPath));
return db;
}
