如何实现一个RadioGroupBox控件
在用户界面中,经常需要这样的逻辑——当选择某个RadioButton时启用一组控件(如TextBox,ComboBox等),当这个RadioButton未被选中时,相应的一组控件被禁用。为求方便,需要UserControl。它具有如下特性:
1、具有一个单选钮
2、能作为一个容器
3、具有GroupBox一样的边框和标题栏
4、具有Checked属性,当未选定单选钮时,其中包含的各控件的Enabled属性为False;而当本UserControl时启用其子控件。
  但其包含的每个子控件的Enabled状态可能不相同,要求能保持子控件的启用/禁用状态。
5、本RadioGroupBox的选定状态可以跟同级的其它RadioGroupBox和RadioButton协调,以便实现单选功能。
如下图所示:


------解决方案--------------------
RadioButton 的选中事件啊,再设置需要的控件的Enable属性的true或者false
------解决方案--------------------
C# code

partial class RadioGroupBox
    {
        /// <summary> 
        /// Required designer variable.
        /// </summary>
        private System.ComponentModel.IContainer components = null;

        /// <summary> 
        /// Clean up any resources being used.
        /// </summary>
        /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }

        #region Component Designer generated code

        /// <summary> 
        /// Required method for Designer support - do not modify 
        /// the contents of this method with the code editor.
        /// </summary>
