I want to know if it is possible to include an application page in another application page?
Basically, I have an application page working with tabs. I would like to have the content change when a tab is clicked. To do this I see two possibilities:
1) Having a placeholder, and on each tab click, refreshing the place holder with the relevant content using C# code behind.
Which solution is the best? Knowing that the contents I'll show are forms, I need to be able to control them with C# code behind.
