WPF故事板開始 - 錯誤

Question

我得到在該行sb.Begin(leftMenu);以下錯誤（SB是一個故事板）：

System.InvalidOperationException：「無法解析的屬性路徑的所有屬性引用‘保證金’。驗證適用的對象是否支持這些屬性。'

的XAML代碼：

Error你得到是因爲margin是不是有效的屬性使用 - >Margin代替

<Window.Resources> 
    <Storyboard x:Key="showMenu"> 
     <ThicknessAnimation Storyboard.TargetProperty="Margin" From="-150,0,0,0" To="0,0,0,0" DecelerationRatio="0.8" Duration="0:0:10"/> 
    </Storyboard> 
    <Storyboard x:Key="hideMenu"> 
     <ThicknessAnimation Storyboard.TargetProperty="Margin" From="0,0,0,0" To="-150,0,0,0" DecelerationRatio="0.8" Duration="0:0:10"/> 
    </Storyboard> 
</Window.Resources> 
<Grid> 
    <StackPanel Panel.ZIndex="2" Name="leftMenu" Orientation="Horizontal" HorizontalAlignment="Left" Background="Yellow" Margin="-150,0,0,0"> 
     <Border BorderBrush="AliceBlue" BorderThickness="1" Width="150" Background="AliceBlue"> 

     </Border> 
    </StackPanel> 
    <Grid> 
     <Button Name="btnHide" Width="50" Click="btnHide_Click" Content="Hide" Visibility="Hidden"/> 
     <Button Name="btnShow" Width="50" Click="btnShow_Click" Content="Hide" Visibility="Visible"/> 
    </Grid> 
</Grid>
