Silverlight Telerik控件学习：弹出窗口RadWindow

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:
