ScriptManager.RegisterClientScriptInclude Method (Page, Type, String, String)

Registers client script with the ScriptManager control every time that an asynchronous postback occurs, and then adds a script file reference to the page.

Namespace:  System.Web.UI
Assembly:  System.Web.Extensions (in System.Web.Extensions.dll)

public static void RegisterClientScriptInclude(
	Page page,
	Type type,
	string key,
	string url
)

Parameters

page
Type: System.Web.UI.Page
The page object that is registering the client script file.
type
Type: System.Type
The type of the client script file. This parameter is usually specified by using the typeof operator (C#) or the GetType operator (Visual Basic) to retrieve the type of the control that is registering the script.
key
Type: System.String
A unique identifier for the script file.
url
Type: System.String
The URL of the script file.

ExceptionCondition
ArgumentNullException

The client script file type is null.

- or -

The page that is registering the script file is null.

ArgumentException

url is null.

- or -

When you register a script file with this method, the script is rendered every time that an asynchronous postback occurs. To register a script file for a control that is inside an UpdatePanel control so that script is registered only when the UpdatePanel control is updated, use the RegisterClientScriptInclude(Control, Type, String, String) overload of this method.

If you want to register a script block that does not pertain to partial-page updates, and if you want to register the script block only one time during initial page rendering, use the RegisterClientScriptBlock method of the ClientScriptManager class. You can get a reference to the ClientScriptManager object from the ClientScript property of the page.
