在地图控件的左下角,有一个展开按钮。单击时,地图控件应扩展为全屏,按钮应更改为折叠按钮。这很容易,但我想为扩展和折叠过程设置动画。我怎么能这样做?

有关XAML元素的动画属性的概述,请查看此处...

对于Map,这里有一些C#代码可以为其“Height”属性设置动画...
// assumes Map element is called 'map'
double height = map.Height;
double from, to;
// animate from 150 to 800, or vice versa
if (height == 150)
{
from = 150;
to = 800;
}
else
{
from = 800;
to = 150;
}
Storyboard sb = new Storyboard();
DoubleAnimation fillHeightAnimation = new DoubleAnimation();
fillHeightAnimation.From = from;
fillHeightAnimation.To = to;
fillHeightAnimation.Duration = new Duration(TimeSpan.FromSeconds(0.3));
Storyboard.SetTarget(fillHeightAnimation, map);
Storyboard.SetTargetProperty(fillHeightAnimation, new PropertyPath("Height"));
sb.Children.Add(fillHeightAnimation);
sb.Begin();
