UpdatePanel and CSS
The ASP.net AJAX UpdatePanel control in RTM unfortunately does not have a CssClass property. A CSS property may be nice to pretty up the UpdatePanel but in my case, I was hoping to use it to set the CSS "visibility" property of an UpdatePanel when the page loads. One could do it using javascript alone but the hide command normally fires when the page load completes which causes the user to catch a glimpse of the element being hidden.

Using the UpdateProgress control as a modal overlay
After reading up on the Extender Control tutorial, I decided to write my first Extender control as a learning exercise.
UpdateProgressOverlayExtender is an ASP.Net AJAX extender that can be attached to any UpdateProgress control in order to position it over any control that you specify. If a control is not specified, the UpdateProgress control is positioned over its AssociatedUpdatePanel. You can even position it over the Form control or the document display area to give a modal effect. The screen capture below shows the UpdateProgress control overlaying a GridView control.
