为什么我的栏不对齐？

Question

使用以下XAML，我得到此布局：

<GroupBox Header="Adres" Grid.Row="1" Grid.RowSpan="5">
    <Grid ShowGridLines="True">
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="Auto"/>
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="150"/>
            <ColumnDefinition Width="*"/>
            <ColumnDefinition Width="*"/>
            <ColumnDefinition Width="*"/>
        </Grid.ColumnDefinitions>
        <Label HorizontalAlignment="Left" Content="Straat:"/>
        <TextBox Margin="130,0,0,0" Text="{Binding Address.Street}" Grid.Column="1" Grid.ColumnSpan="3" />

        <Label HorizontalAlignment="Left" Grid.Row="1" Content="Nr:"/>
        <TextBox Margin="130,0,0,0" Text="{Binding Address.Number}" Grid.Row="1" Grid.Column="1" Grid.ColumnSpan="2" />
        <Label HorizontalAlignment="Left" Grid.Row="1" Content="Ext:" Grid.Column="3"/>
        <TextBox Margin="130,0,0,0" Text="{Binding Address.NumberExtension}" Grid.Row="1" Grid.Column="3" />

        <Label HorizontalAlignment="Left" Content="Gemeente:" Grid.Row="2"/>
        <ComboBox ItemsSource="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type ListView}}, Path=DataContext.Towns}" Grid.Row="2" Grid.Column="1" HorizontalAlignment="Stretch">
        </ComboBox>
        <ComboBox ItemsSource="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type ListView}}, Path=DataContext.Towns}" Grid.Row="2" Grid.ColumnSpan="2" Grid.Column="2">
        </ComboBox>

        <Label Width="125" HorizontalAlignment="Left" Content="Land:" Grid.Row="3"/>
        <TextBox Margin="130,0,0,0" Text="{Binding Address.Country}" Grid.Column="1" Grid.ColumnSpan="3" Grid.Row="3" />
    </Grid>
</GroupBox>

为什么我的文本框与我所做的列不对齐？ 为何组合框确实与列对齐？

Answer 1

似乎您的文本框中的边距设置有误，导致其位置与网格的列未对齐。
