Doe的任何人都知道下面的标记有什么问题

<UserControl

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    x:Class="DoubleAnim.MainPage"
    Width="640" Height="480">
    <UserControl.Resources> 
        <Storyboard x:Name="Storyboard1">
            <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(Canvas.Left)" Storyboard.TargetName="objectToAnimate">
                <EasingDoubleKeyFrame KeyTime="0" Value="0"/>
                <EasingDoubleKeyFrame KeyTime="0:0:1" Value="400"/>
            </DoubleAnimationUsingKeyFrames>                
        </Storyboard>
    </UserControl.Resources>

    <Grid x:Name="LayoutRoot" Background="White">
        <Rectangle x:Name="objectToAnimate" Fill="#FF0000F9" HorizontalAlignment="Left"  Canvas.Top="164"  Height="100" Stroke="Black" VerticalAlignment="Top" Width="192" RadiusY="8" RadiusX="8" >

        <Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="132,180,0,0" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" />
    </Grid>
</UserControl>

一切看起来都不错但不起作用:(（ Doe的silverlight知道如何为canvas.top和canvas.left制作动画？或者也许我错过了什么？

Answer 1

你需要一个画布对象。用画布替换网格。

Answer 2

Canvas.Top和Canvas.Left附加属性仅在Rectangle（或UIElement）托管在Canvas面板中时使用。 Grid使用不同的逻辑和附加属性来布局它的子项。
