本文探讨了在WPF应用中，如何实现RadioButton在不同页面调用时，通过动态指定组名，确保每次调用时仅一组RadioButton项被选中。通过实例展示了如何在多个页面上使用RadioButton并正确设置组名，以避免多次调用中出现多项同时被选中的情况。

在做项目中碰到一个问题，一组RadioButton被同一个页面调用多次，发现调用多次中只一组的RadioButton某一项被选中。但是如果是CheckBox
可以多次被选中，那需要每次动态指定RadioButton的GroupName,看如下例子。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;

namespace WpfApplication1
{
    /// <summary>
    /// UserControl1.xaml 的交互逻辑
    /// </summary>
    public partial class UserControl1 : UserControl
    {
        public UserControl1(int i)
        {
            InitializeComponent();

            switch (i)
            {
                case 0:
                      rb.GroupName = "0";
                    xx.GroupName = "0";
                    rr.GroupName = "0";
                    break;
                  
                case 1:
                    rb.GroupName = "1";
                    xx.GroupName = "1";
                    rr.GroupName = "1";
                    break;
                case 2:
                          rb.GroupName = "2";
                    xx.GroupName = "2";
                    rr.GroupName = "2";
                    break;
            }
            this.Loaded += new RoutedEventHandler(UserControl1_Loaded);
        }

        void UserControl1_Loaded(object sender, RoutedEventArgs e)
        {
            rb.IsChecked = true;
            ckb.IsChecked = true;

        }
    }
}

using System.Windows.Data;

namespace WpfApplication1
{
    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            this.Loaded += new RoutedEventHandler(MainWindow_Loaded);
           
           
        }

        void MainWindow_Loaded(object sender, RoutedEventArgs e)
        {          
            sp.Children.Add(new UserControl1(0));
            sp.Children.Add(new UserControl1(1));
            sp.Children.Add(new UserControl1(2));

        }
    }
}
