本文深入探讨了RadioButton控件在WPF应用中的使用，详细介绍了Grouping属性的作用及其在实现单选功能时的重要性。通过具体示例展示了如何通过事件处理程序响应RadioButton的Checked事件，实现用户交互和数据更新。

    Public Sub New()
        InitializeComponent()
    End Sub

    Private Sub RadioButton1_Checked(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles RadioButton1.Checked
        Label1.Content = RadioButton1.Content
        listbox_add(Label1.Content)
    End Sub

    Private Sub RadioButton2_Checked(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles RadioButton2.Checked
        Label1.Content = RadioButton2.Content
        listbox_add(Label1.Content)
    End Sub

    Private Sub RadioButton3_Checked(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles RadioButton3.Checked
        Label1.Content = RadioButton3.Content
        listbox_add(Label1.Content)
    End Sub
    Private Sub listbox_add(stritem As String)
        ListBox1.Items.Add(stritem)
    End Sub
End Class
