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)

public:
static void RegisterOnSubmitStatement(
	Page^ page,
	Type^ type,
	String^ key,
	String^ script
)

Parameters

page
Type: System.Web.UI::Page^

The page object that is registering the onsubmit statement.

type
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.

key
Type: System::String^

A unique identifier for the script statement.

script
Type: System::String^

The script to register.

Exception Condition
ArgumentNullException

page is null.

- or -

type is null.

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

System_CAPS_noteNote

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.
