ASP.NET ModalDialog with PostBack and

We have gotten a lot of posts asking how to create Modal Dialogs and return the entered values back to the spawning page when the window is closed. In addition, people are sometimes confused into believing that a Modal Dialog window cannot handle ASP.NET Postbacks. This is not true. A Modal Dialog is just a type of HTML page that won't let you return to the page that created it until you close the window. Otherwise, except for a few minor "gotchas", it's no different than any other HTML page. It can certainly be an ASP.NET page, there is no great hangup with that.
