ScriptManager : The ScriptManager control is the first AJAX server control in the toolbox. This control helps in implementing the ajax functionality in the asp.net website. You need to place this control on the webpage wherever AJAX functionality is required. In the absence of this control, no other Ajax server controls, such as Timer, UpdatePanel and UpdateProgress , can be added to the webpage. The ScriptManager control is responsible for managing client scripts for AJAX-enabled website . The Script Manager control use a ScriptManager class to manage AJAX script libraries and script files.

In this scenario , you need to use the Timer control . The Timer control contains a property named interval and an event named Tick.. The Interval property of the timer control is used to specify the desired time limit in second.
