ScriptManager.RegisterOnSubmitStatement Method (Control, 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)

Type: System.Web.UI.Control
The control 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.

A unique identifier for the script statement.

control is not in the page's control tree.

The RegisterOnSubmitStatement adds script that is executed before the form is submitted, which lets you modify the submission or cancel it.

You use the RegisterOnSubmitStatement method to render an onsubmit statement that is compatible with partial-page rendering and that has no Microsoft Ajax Library dependencies. JavaScript code that is registered by using this method is sent to the page only when the control that is registering the statement is inside an UpdatePanel control that is being updated. To register code with every asynchronous postback, use the RegisterOnSubmitStatement(Page, 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.

The script parameter of the RegisterOnSubmitStatement method can contain multiple script commands that are delimited by using semicolons (;).
