Page.RegisterStartupScript Method (String, String)
Emits a client-side script block in the page response.
Assembly: System.Web (in System.Web.dll)
[ObsoleteAttribute("The recommended alternative is ClientScript.RegisterStartupScript(Type type, string key, string script). http://go.microsoft.com/fwlink/?linkid=14202")] public virtual void RegisterStartupScript( string key, string script )
Similar to the RegisterClientScriptBlock method, the method emits the script just before the closing tag of the Page object's <form runat= server> element. Be sure to include opening and closing <script> elements around the script block string specified in the script parameter.
Because this method uses a key to identify the script block, the script block does not have to be emitted to the output stream each time it is requested by a different server control instance
Any script blocks with the same key parameter values are considered duplicates.
Remember to include HTML comment tags around your script so that it will not be rendered if the requesting browser does not support scripts.
