Questions tagged [scriptmanager]

ScriptManager is an ASP.NET control that manages ASP.NET Ajax script libraries and is used for Ajax enabled controls, such as UpdatePanels

ScriptManager is an ASP.NET control that manages ASP.NET Ajax script libraries. The ScriptManager performs the following functions.

  1. Enables partial page rendering
  2. Enables client side script access to web services
  3. Enables use of authentication and profile services from the client

Only one ScriptManager can be allowed per page. For scenarios where a second ScriptManager reference is required, such as within an usercontrol, the ScriptManagerProxy control should be used.
