如何对此groupeBox进行CheckedChanged事件

我通常通过点击按钮来制作事件，虽然我不能通过点击groupeBox来制作CheckChanged事件；它会生成一个单击事件或输入事件

我还添加了我的讲师代码

// Using RadioButtons to set message window options.
using System;
using System.Windows.Forms;

namespace RadioButtonTest
{
    // Form contains several RadioButtons--user chooses one
    // from each group to create a custom MessageBox

      // create variables that store the user's choice of options
      private MessageBoxIcon iconType;
      private MessageBoxButtons buttonType;

      // default constructor
      public RadioButtonTestForm()
      {
         InitializeComponent();
      } // end constructor

      // change Buttons based on option chosen by sender
      private void buttonType_CheckedChanged( 
         object sender, EventArgs e )
      {
         if ( sender == okRadioButton ) // display OK Button

CheckedChanged

事件在单选按钮上，而不是在分组框上。但您可以做的是将所有单选按钮指向同一个处理程序。如果转到“属性”窗口中的事件列表，则会出现一个小的闪电图标。单击该按钮，您将获得所有事件的列表，您可以在其中为所有事件选择相同的处理程序。

如何使用我的行业工具

。在单选按钮上单击鼠标右键。选择属性，选择事件窗口（属性窗口中的Lightning图标）搜索CheckedChanged事件并双击它……我的问题是，我认为添加到groupBox的所有组件都将是该groupBox的一部分。现在我想检查GroupBox的CheckedChanged，而不是单选按钮。你能说怎么做吗@MediaDepp没有适用于您的GroupBox的CheckedChanged EventHandler，正如其他人所说，它位于单选按钮上。当您将项目放置在容器中时，容器不会继承包含的项目的事件。然后您可能需要考虑将此标记为正确答案。
