WPF TextBlock高度

Question

我正在动态添加TextBlocks，但是高度有问题。

有时文本会出现剪切。 此外，似乎该应用程序为所有元素分配了相同的高度。

XAML：

<ScrollViewer Grid.Column="2" x:Name="DetailInfoScroll"  
              Margin="25,0,50,0"
              Style="{StaticResource HorizontalScrollViewerStyle}">
    <VariableSizedWrapGrid Grid.Column="2" Margin="25,0,50,35" 
                           HorizontalAlignment="Left"  
                           VerticalAlignment="Center" 
                           x:Name="StkText">                      
    </VariableSizedWrapGrid>
</ScrollViewer>

和代码：

var txt = new TextBlock
{
    Text = text,
    TextWrapping = TextWrapping.Wrap,
    TextAlignment = TextAlignment.Justify,
    FontSize = 14,
    Margin = new Thickness(0, 0, 25, 15),
    MaxWidth = 400,
    LineStackingStrategy = LineStackingStrategy.MaxHeight,
    VerticalAlignment = VerticalAlignment.Center,
    HorizontalAlignment = HorizontalAlignment.Left
};

txt.Measure(new Size(Double.PositiveInfinity, Double.PositiveInfinity));
var desiredSizeNew = txt.DesiredSize;
txt.Height = desiredSizeNew.Height;

StkText.Children.Add(txt);

不知道这是否是完美的解决方案，但是我找到了一种使height属性不锁定到该行中各列的方法。 这样做的问题是，在将任何内容放入第二列之前，它将一直沿第一列向下移动。 如果WrapPanel不能将所有高度锁定在同一行中，就无法轻松地水平添加元素。

通过使用样式，这也摆脱了您的代码。

这是一个正在使用的例子

<Window.Resources>
    <Style TargetType="TextBlock">
        <Setter Property="Width" Value="400"/>            
        <Setter Property="Foreground" Value="White"/>
        <Setter Property="FontSize" Value="14"/>
        <Setter Property="TextWrapping" Value="Wrap"/>  
        <Setter Property="Margin" Value="10"></Setter>
    </Style>
</Window.Resources>
<WrapPanel Orientation="Vertical" Width="850" Background="Black" Height="300" >
    <TextBlock Text="Focus on questions about an actual problem you have faced. Include details about what you have tried and exactly what you are trying to do."/>
    <TextBlock Text="Not all questions work well in our format. Avoid questions that are primarily opinion-based, or that are likely to generate discussion rather than answers."/>
    <TextBlock Text="Questions that need improvement may be closed until someone fixes them."/>
    <TextBlock Text="All questions are tagged with their subject areas. Each can have up to 5 tags, since a question might be related to several subjects. Click any tag to see a list of questions with that tag, or go to the tag list to browse for topics that interest you."/>
    <TextBlock Text="Your reputation score goes up when others vote up your questions, answers and edits."/>        
</WrapPanel>
