WPF控件组

Question

例如我有这样的xaml代码：

<Window x:Class="SwitchingControl.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <Grid>
            <Grid.RowDefinitions>
                <RowDefinition Height="auto"/>
                <RowDefinition/>
            </Grid.RowDefinitions>
            <Grid.ColumnDefinitions>
                <ColumnDefinition/>
                <ColumnDefinition/>
            </Grid.ColumnDefinitions>
            <Grid Grid.ColumnSpan="2">
                <StackPanel Orientation="Horizontal">
                    <RadioButton Content="First"></RadioButton>
                    <RadioButton Content="Second"></RadioButton>
                    <RadioButton Content="Third"></RadioButton>
                </StackPanel>
            </Grid>
            <Grid Grid.Row="1">
                <Grid.RowDefinitions>
                    <RowDefinition Height="auto"></RowDefinition>
                    <RowDefinition Height="auto"></RowDefinition>
                    <RowDefinition Height="auto"></RowDefinition>
                    <RowDefinition Height="auto"></RowDefinition>
                    <RowDefinition Height="auto"></RowDefinition>
                    <RowDefinition Height="auto"></RowDefinition>
                    <RowDefinition Height="auto"></RowDefinition>
                    <RowDefinition Height="auto"></RowDefinition>
                </Grid.RowDefinitions>
                <Label Content="First" Grid.Row="0" ></Label>
                <Label Content="Second" Grid.Row="1"></Label>
                <Label Content="First" Grid.Row="2"></Label>
                <Label Content="Second" Grid.Row="3"></Label>
                <Label Content="Third" Grid.Row="4"></Label>
                <Label Content="Third" Grid.Row="5"></Label>
                <Label Content="Second" Grid.Row="6"></Label>
            </Grid>
        </Grid>
    </Grid>
</Window>

我需要检查内容为First First RadioButton的标签。如果Second被检查，则内容为Second RadioButton的标签。 标签数量为70-100的主要问题。是否有一些优雅的简单方法来实现它？
