ScriptManagerNotFoundException: The Report Viewer Web Control requires a System.Web.UI.ScriptManager on the web form.

If you get this error after add a new report viewer to a web page, you must add a ScriptManager from “AJAX Extensions” in the toolboox. This will correct this error.

Si le sale este error luego de adicionar un report viewer en la página web, debe adicionar un ScriptManager desde “AJAX Extensions” de la caja de herramientas. Esto corregirá el error.
