An UpdateProgress Control in Modal Popup Style with Atlas
Introduction
Atlas (ASP.NET AJAX) has this cool
UpdateProgress control which provides a visual
indicator while one or more of the
UpdatePanel controls are being updated. This
UpdateProgress control is great, but in some
cases, I want all other elements on the page be disabled
when the UpdateProgress is shown. Basically, I
want the UpdateProgress to act as something
like a modal popup. That led me to build this
ModalUpdateProgress control.
