Vertically aligning Labels and TextBlocks at Top in XAML

问题

How can I vertically align a Label and TextBlock at Top so that their first lines of text line up?

<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="Auto" />
        <ColumnDefinition />
    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
        <RowDefinition />
    </Grid.RowDefinitions>
    <Label Grid.Column="0" VerticalAlignment="Top">Some Label:</Label>
    <TextBlock Grid.Column="0" VerticalAlignment="Top">Some text<TextBlock>
</Grid>

The above code gives me this:

回答1:

The extra space around the label comes from the Padding property. To remove the space, you can explicitly set the Padding property to "0" directly on the Label, or, of course, set it via a Style.

<TextBlock>
<InlineUIContainer BaselineAlignment="Top"><Label Content="Label"/></InlineUIContainer>
<InlineUIContainer BaselineAlignment="Top"><TextBlock>TextBlock Content</TextBlock>                 </InlineUIContainer>
</TextBlock>

HTH.

Here is a workaround: Align bottoms of text in controls.
