大家好日子， 我很难找到有关如何在silverlight中创建这种酷炫效果的信息。谁能帮我吗？ 这是一个闪存网站的链接，具有我需要的效果。 http://www.marcecko.com/#/

我也非常喜欢这个效果，所以我使用行为重新创建了它：
public class PanBehavior : Behavior<ScrollViewer>
{
protected override void OnAttached()
{
this.AssociatedObject.MouseMove += new MouseEventHandler(AssociatedObject_MouseMove);
this.AssociatedObject.VerticalScrollBarVisibility = ScrollBarVisibility.Hidden;
this.AssociatedObject.HorizontalScrollBarVisibility = ScrollBarVisibility.Hidden;
}
void AssociatedObject_MouseMove(object sender, MouseEventArgs e)
{
var mousePos = e.GetPosition(this.AssociatedObject);
double panningY = this.AssociatedObject.ExtentHeight - this.AssociatedObject.ViewportHeight;
double panningX = this.AssociatedObject.ExtentWidth - this.AssociatedObject.ViewportWidth;
double relativeMouseY = mousePos.Y / this.AssociatedObject.ActualHeight;
double relativeMouseX = mousePos.X / this.AssociatedObject.ActualWidth;
panningY *= relativeMouseY;
panningX *= relativeMouseX;
this.AssociatedObject.ScrollToVerticalOffset(panningY);
this.AssociatedObject.ScrollToHorizontalOffset(panningX);
}
}
只需将此行为添加到任何ScrollViewer，它就可以正常工作。例如，这个xaml：
<Grid>
<ScrollViewer>
<i:Interaction.Behaviors>
<local:PanBehavior />
</i:Interaction.Behaviors>
<UniformGrid Width="1000" Height="1000" Rows="10" Columns="10">

请注意，我仅在WPF中对此进行了测试，但它在Silverlight中的工作方式基本相同。 --EDIT--用两种技术测试它。
+1很酷的问题！ ：）
