I have an application that loads data from an XML file. The data sections are tab controlled and separated by folders. Each folder is a different "site" with it's OWN xml file. The application only loads data when I select a "site"
and only THAT site's data is loaded. The problem is that ALL the data loads at the same time. I want the data to load based on the tab. So when I click the "General" tab only the "General" data is loaded and so forth.
How do I accomplish this?
