限制Silverlight中TextBlock的寬度

顯而易見的MaxWidth會被忽略，即使此文本繼續超過父容器控件（位於silverlight區域的邊緣），「DisplayBox」TextBlock中的文本也會顯示整個文本。限制Silverlight中TextBlock的寬度

<win:HierarchicalDataTemplate x:Key="hierarchicalTemplate" ItemsSource="{Binding _children}"> 
    <Border BorderThickness="0" BorderBrush="Orange" HorizontalAlignment="Stretch" Background="{Binding Converter={StaticResource BackgroundConverter}}"> 
     <toolkit:DockPanel LastChildFill="True" Width="{Binding HeirarchyLevel, Converter={StaticResource WidthConverter}}" Height="20"> 
      <Canvas toolkit:DockPanel.Dock="Right" Width="20" MouseLeftButtonUp="Arrow_MouseLeftButtonDown">

你可以切換到使用一個網格，而不是一個帆布？一個TextBlock會當它是一個網格的孩子進行適當剪裁。這不是畫布的真實。

 <Canvas Width="Auto" Loaded="TextArea_Loaded"> 
**<Border>**      
<TextBlock Name="DisplayBox" FontFamily="Arial" FontSize="17" Foreground="Black" Width="Auto" Text="{Binding TaskName}" MouseLeftButtonUp="TextBlock_MouseLeftButtonUp" /> 
        <TextBox Name="EditBox" FontFamily="Arial" FontSize="10" Foreground="Black" Height="20" Text="{Binding TaskName}" Visibility="Collapsed" LostFocus="TextBox_LostFocus" /> 
        <Line Stroke="Black" X1="0" Y1="10" X2="202" Y2="10" Width="Auto" /> 
**</Border>** 
       </Canvas>

也應該工作。（邊框將會標籤的最大長度，而邊框本身將不可見其厚度爲0.
