This class allows creating a modal dialog that hides the background of the Web page using an opaque overlay and then pops an HTML element of your choice on top of it. The element (typically a Div tag) should also contain a button or hyper link used to close the dialog.

The control works by being assigned an HTML DOM element Id that acts as the dialog, plus at least one 'button' object that can be clicked to close the dialog. You can use two different buttons (okButtonId/cancelButtonId) and route the clicks to an event handler of your choice.

More info on operation can be found here.
