ScriptManager.RegisterClientScriptBlock Method (Page, Type, String, String, Boolean)

Registers a client script block with the ScriptManager control for use with a control that is inside an UpdatePanel control, and then adds the script block to the page.

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

public static void RegisterClientScriptBlock(
	Page page,
	Type type,
	string key,
	string script,
	bool addScriptTags
)

Parameters

page
Type: System.Web.UI.Page

The page object that is registering the client script block.

type
Type: System.Type

The type of the client script block. 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 block.

script
Type: System.String

The script to register.

addScriptTags
Type: System.Boolean

true to enclose the script block in <script> and </script> tags; otherwise, false.

ExceptionCondition
ArgumentNullException

The script block type is null.

- or -

The page that is registering the script block is null.

When you register a script block by using this method, the script is rendered every time that an asynchronous postback occurs. To register a script block for a control that is inside an UpdatePanel control so that script is registered only when the UpdatePanel control is updated, use the RegisterClientScriptBlock(Control, Type, String, String, Boolean) 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.
