Remarks
You use the RegisterClientScriptInclude method to register a client script file for a page or part of a page that is participating in partial-page updates. Client script files that are registered by using this method are sent to the page only when the control represents a control that is inside an UpdatePanel control that is being updated. To register a script file every time that an asynchronous postback occurs, use the RegisterClientScriptInclude(Page, Type, String, String) 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 RegisterClientScriptInclude method registers a client script file on the page by rendering a script element whose opening tag contains a src attribute. The url parameter is used to set the src attribute. To resolve URLs, use the ResolveClientUrl method. This method uses the context of the URL it is called for to resolve the path.
Both the RegisterClientScriptInclude and RegisterClientScriptResource methods render script files to 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 rendered, the script is not rendered again.

Remarks
When you register a script file with this method, the script is rendered every time that an asynchronous postback occurs. To register a script file for a control that is inside an UpdatePanel control so that script is registered only when the UpdatePanel control is updated, use the RegisterClientScriptInclude(Control, Type, String, String) 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.
