几乎所有的业务系统都有弹出窗口，典型场景有二种 ：
1、简单的弹出一个对话框显示信息，比如下面这样：
这个很简单，代码示例如下：
DialogParameters pars = new DialogParameters(); pars.Header = "信息"; pars.Content = "Hello World"; RadWindow.Alert(pars);
2、点击某条记录的“编辑”按钮，传入ID参数，弹出一个窗口，编辑保存后，将操作结果返回给父窗口
这种场景下，要求:
a)弹出窗口能接受到父窗口传过来的参数
b)弹出窗口关闭时，父窗口要能区分出是通过什么操作关闭的(比如：是直接点击右上角的X按钮关的，还是点击“提交”按钮关的，或是点击“取消”按钮关的)
c)弹出窗关闭后，父窗口要能知道操作结果
示例代码如下:
