Set and Get Modal Dialog Data
This is an article on how to set/get data on a modal dialog popup:
http://www.codeproject.com/aspnet/Modal_Dialog.asp
I'm trying to change the controls from HTML to ASP.NET but the code I wrote doesn't work. The reason I used JavaScript like in the article is I don't know of a way to refer to a pages controls from another page in my code.
Thanks.
