Question

网格上有两个按钮。在右侧按钮上应该显示左对齐的一些文本和右对齐的另一个文本。到目前为止，在我所有的尝试中，两个字符串都位于按钮的中心，而不是左右。

一旦解决了这个问题，我需要在文本和按钮左/右边框之间留出一些空间。谁可以帮忙？

我的XAML代码到目前为止开始：

不要责怪我不把这些东西放在ResourceDictionary中。只是想让这个例子变得简单。

您需要将HorizontalContentAlignment="Stretch"添加到Button，以便内容占用全部空间。之后，要在文本和按钮边框之间留出空间，只需在第一个和最后一个位置再添加两个网格列。

XAML：

<UserControl x:Class="MyNamespace.MyClass"
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
     xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
     xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
     mc:Ignorable="d" 
     d:DesignHeight="300" d:DesignWidth="900">
<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="3*"/>
        <ColumnDefinition Width="1*"/>
    </Grid.ColumnDefinitions>
    <Button>
        <TextBlock Text="left button"></TextBlock>
    </Button>
    <Button Grid.Column="1" HorizontalContentAlignment="Stretch">
        <Grid>
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="10"/>
                <ColumnDefinition Width="Auto"/>
                <ColumnDefinition Width="*"/>
                <ColumnDefinition Width="Auto"/>
                <ColumnDefinition Width="10"/>
            </Grid.ColumnDefinitions>
            <TextBlock Text="left" Grid.Column="1"></TextBlock>
            <TextBlock Text="right" Grid.Column="3"></TextBlock>
        </Grid>
    </Button>
</Grid>

在网格中的按钮上调整TextBlock
