How To: Modal Dialogs in ASP.NET

This tutorial begins with basic HTML showing how to set data on a Modal Dialog and return that data to the original page using Javascript. There are a few tricks which will be illustrated that you'll have to use if you want to get the same functionality with ASP.NET pages. I've seen similar tutorials and samples on the web. Some claim to have modal dialogs but still allow clicking on the main window. Most don't show how to return multiple values from the dialog. Included in the .zip file is a web page called Instructions.htm which (you guessed it) includes tutorial instructions. The HTML source is in the HTML directory and the ASP.NET (C#) Project is in the DialogAspx directory. I have only tested on Internet Explorer 6.0 but I believe it will also work on IE 5.0. Please rate and post comments. Enjoy!
