WPF 实现文字上翻效果

Question

刚学WPF，现在想实现以下功能：
   如，有3行文字，实现上翻，每次显示一条内容。请高手指点以下，最好给个代码。

Answer 1

TranslateTransform
代码还是留给你自己写吧

Answer 2

最简单的方法设置一个timer
每过一段时间改变下texblock.text

Answer 3

类似office2010启动时的状态文字那样？

Answer 4

这是我写的，但是还没有满足我想要的，就是：2条数据连续出现。现在是第一次循环完后，就乱了。
帮我看看哪里有问题。谢谢了。    <Canvas x:Name="a" VerticalAlignment="Top" Background="Black">

<Canvas VerticalAlignment="Top" Height="46" ClipToBounds="True">
    <StackPanel Name="content1">
        <StackPanel.RenderTransform>
            <TranslateTransform Y="0" />
        </StackPanel.RenderTransform>

Answer 6

如果有多个内容要滚动显示，那么每次都要动态画多个TextBlock 吗？
还是只画几个TextBlock ，然后动态修改其内容啊。

Answer 7

同为WPF新手，学习一下。
另外顶nonocast大牛

Answer 8

互相学习
在后台往content1里面加TextBlock即可

Answer 9

郁闷了，我用的是lable ，然后读取txt文档内容，用跑马灯效果显示txt文档内容。
遇到一个问题，就是有没有办法根据读到的内容，让lable自动调整宽度。我好设置from 和 to 啊，让这段文字能刚好跑完。 我现在的做法是 取得文字的 字节数 * 字体大小 来设置lable宽度。这样不准啊。
有没有 AoutSize 一样的属性啊。 或者怎么能计算出lable的宽度啊。

Answer 10

Binding Label的ActualHeight不就ok了

Answer 11

还是不行，看看下面：    <Grid>
        <Label  Height="32" Background="Red" HorizontalAlignment="Left" Name="marquee" VerticalAlignment="Top" Width="{Binding Path=ActualWidth}">
            <Label.RenderTransform>
                <TranslateTransform x:Name="lab"/>
            </Label.RenderTransform>
        </Label >
        <Button Content="Button" Height="30" HorizontalAlignment="Left" Margin="60,203,0,0" Name="button1" VerticalAlignment="Top" Width="138" Click="button1_Click" />
    </Grid>        public void run()
        {
            this.marquee.Content = "!啊啊啊啊啊啊啊啊啊啊啊啊啊啊啊啊啊!";
            int intRuntime = 10;            DoubleAnimation animation = new DoubleAnimation();
            animation.Duration = TimeSpan.FromSeconds(intRuntime);
            animation.From = this.marquee.ActualWidth;
            animation.To = -this.marquee.ActualWidth;
            Storyboard.SetTargetName(animation, "lab");
            Storyboard.SetTargetProperty(animation, new PropertyPath(TranslateTransform.XProperty));            story.Duration = TimeSpan.FromSeconds(intRuntime);
            story.Children.Add(animation);            story.RepeatBehavior = RepeatBehavior.Forever;
            story.Begin(this);
        }        private void button1_Click(object sender, RoutedEventArgs e)
        {
            run();
        }
