在Silverlight中实现marquee的效果

在XAML中，添加如下代码：

 

<ScrollViewer HorizontalScrollBarVisibility="Hidden" VerticalScrollBarVisibility="Hidden" BorderThick<a href="/tag/nes/" target="_blank" class="keywords">nes</a>s="0" Height="36"> <Canvas Loaded="MarqueeControl_Loaded" Width="592" HorizontalAlignment="Left"> <Canvas.Resources> <Storyboard x:Name="sb"> <DoubleAnimation x:Name="da" BeginTime="00:00:02" Storyboard.TargetName="txtLorem" Storyboard.TargetProperty="(Canvas.Left)" From="0" RepeatBehavior="Forever"/> </Storyboard> </Canvas.Resources> <TextBlock x:Name="txtLorem" Width="596" Height="33" Text="滚动<a href="/tag/wenzi/" target="_blank" class="keywords">文字</a><a href="/tag/neirong/" target="_blank" class="keywords">内容</a>..."/> </Canvas> </ScrollViewer>

 

在c#里创建相应的方法：

 

void MarqueeControl_Loaded(object sender,RoutedEventArgs e) { var canvas = sender as Canvas; if (txtLorem.ActualWidth <= canvas.Width) return; const double speed = 50; da.To = -txtLorem.ActualWidth; da.Duration = new Duration(TimeSpan.FromSeconds(txtLorem.ActualWidth / speed)); sb.Begin(); }

窗体加载的时候：

给把要显示的文字赋值给txtLorem: this.txtLorem.Text = "滚动文字。。。。。";
