ScriptManager.RegisterClientScriptResource Method (Control, Type, String)
Registers the client script that is embedded in an assembly with the ScriptManager control for use with a control that is participating in partial-page rendering.
Assembly: System.Web.Extensions (in System.Web.Extensions.dll)
public static void RegisterClientScriptResource( Control control, Type type, string resourceName )
- Type: System.Web.UI.Control
The control that is registering the script.
- Type: System.Type
The type of the client script. 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
An identifier for the resource.
You use the RegisterClientScriptResource method to register a script that is compatible with partial-page rendering and that has no Microsoft Ajax Library dependencies. Script resources that are registered by using this method are registered only when control represents a control that is inside an UpdatePanel control that is updated. To register a script every time that an asynchronous postback occurs, use the RegisterStartupScript(Page, 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.
The RegisterClientScriptResource method is used when resources from assemblies are accessed through an HTTP handler. This method includes the content of the resource URL in a script element.
Both the RegisterClientScriptInclude and the RegisterClientScriptResource method load script files into the browser. If a script with the same type and key (for a script file) or the same type and resource name (for an embedded resource) is already loaded, the script is not reloaded.
