ASP.NET server control to insert a client script. The first method is to insert the client script block using the RegisterStartupScript () and registerclientscriptblock () methods of the PAGE class. The second method is to add a client script to the attribute of the HTML element. The latter is completed by overlying the AddAttributeStorender () method of the web server control and using the HTMLTextWriter's addAttribute () method.
