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

Registers ECMAScript (JavaScript) code with the ScriptManager control for a control that is used with an UpdatePanel control that is executed when the form is submitted.

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

static member RegisterOnSubmitStatement : 
        page:Page * 
        type:Type * 
        key:string * 
        script:string -> unit


Type: System.Web.UI.Page

The page object that is registering the onsubmit statement.

Type: System.Type

The type of the client script statement. 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.

Type: System.String

A unique identifier for the script statement.

Type: System.String

The script to register.


page is a null reference (Nothing in Visual Basic).

- or -

type is a null reference (Nothing in Visual Basic).

Registering JavaScript code with this method causes the script to be included every time that an asynchronous postback occurs.


Code from any earlier asynchronous postbacks is not removed. New asynchronous postbacks append code to any existing code for the onsubmit statement.

To register code for a control that is inside an UpdatePanel control so that the code is registered only when the UpdatePanel control is updated, use the RegisterOnSubmitStatement(Control, Type, String, String) overload of this method.

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