Writing code that coordinates between server and client to update only specified parts of a Web page usually requires in-depth knowledge of ECMAScript (Java Script).

However, by using the control, you can enable a Web page to participate in partial-page updates without writing any client script.

If you want, you can add custom client script to enhance the client user experience.

When you use an server control and the client Page Request Manager class.

Timer controls allow you to do postbacks at certain intervals.

If used together with Update Panels, which is the most common approach, it allows for timed partial updates of your page, but it can be used for posting back the entire page as well.

The Timer control uses the interval attribute to define the number of milliseconds to occur before firing the Tick event.

As you can see from our Code Behind code listing, we just update the Date Stamp Label each time the Timer fires.

Make sure you find an image (perhaps from a stock image site) that doesn’t have any usage restrictions. The z-index positions the full-screen div on top of all the other elements, hiding them behind it while they load.
