我该如何执行以下操作:
<Window x:Class="MyClientsWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Login" WindowStartupLocation="CenterScreen"
SizeToContent="WidthAndHeight"
MaxWidth="800" MaxHeight="600">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" Name="labelColumn"/>
<ColumnDefinition Width="2*" Name="entryColumn"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Row="0" Text="First name: " Name="firstNameLabel"
Margin="4" VerticalAlignment="Center"/>
<TextBox Grid.Row="0" Grid.Column="1"
Margin="4" HorizontalAlignment="Stretch" />
<TextBlock Grid.Row="1" Text="Last name: " Name="lastNameLabel"
Margin="4" VerticalAlignment="Center"/>
<TextBox Grid.Row="1" Grid.Column="1"
Margin="4" HorizontalAlignment="Stretch" />
</Grid>
第二列的宽度必须是第一列的两倍,但第一列的宽度是自动的,取决于字体系列、字体大小等。此外,调整窗口大小时需要拉伸第二列。
