String^ key,
String^ script
)
JSharp
Parameters
- page (Page)
The Page object that is registering the OnSubmit statement.
- type (Type)
The type of the client script statement. This parameter is usually specified by using the typeof (C# Reference) operator (C#) or the GetType Operator operator (Visual Basic) to retrieve the type of the control that is registering the script.
- key (String)
The string that uniquely identifies the script statement.
- script (String)
The script literal.
Remarks
Registering JavaScript code with this method causes the script to be included each time an asynchronous postback occurs.
noteCode from previous asynchronous postbacks is not removed. New asynchronous postbacks append code to any existing code of 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 are registering a script file that does not pertain to partial-page updates and you want to register a script file only one time during initial page rendering, use the RegisterOnSubmitStatement(String, String) method of the ClientScriptManager class. You can get a reference to the ClientScriptManager object from the ClientScript property of the page.
