Silverlight telerik Control Learning: radwindow

Almost all business systems have pop-up windows. There are two typical scenarios:

1. A dialog box is displayed, such as the following:

This is simple,CodeExample:

 
Dialogparameters pars = new dialogparameters (); pars. header = "information"; pars. content = "Hello World"; radwindow. Alert (PARs );
 

2. Click the "edit" button of a record to input the ID parameter. A window is displayed. After the record is edited and saved, the operation result is returned to the parent window.

In this scenario, the following requirements are required:

A) parameters passed by the parent window can be received in the pop-up window.

B) when the pop-up window is closed, the parent window should be able to differentiate what operations are used to close the window (for example, directly click the X button in the upper right corner to close the window, click Submit or cancel)

C) after the pop-up window is closed, the parent window should be able to know the operation result.

The sample code is as follows:
