It's kind of difficuly to explain but I'll give it a try. I try to create a kind of workflow application. The user get's a question and depending on his answer he gets another question. This flow can become very complicated. What I need to do is create a dynamic form with (for example) a dropdown. when the user select something the next formfield appears, and so on, and so on.

At this moment I try to create the form with asp and hidden div's. When the user selects something another div is shown. But this approach is getting way to complicated. It ends up in a lot of if and case statements.

What can be a better approach in this sitiuation? I do not want refresh the whole page each time.

Maybe a wizard like solution will be better?

Couple of things to consider:
1) I agree, don't refresh the page every time. All you want is to append to the DOM tree the next question, for example you can easily do this with jqeury and ajax;
2) Instead of keeping the logic in code, keep it in data. This way you can avoid nested if-else. Depend on the flow of questions, if it is tree like, keep it in XML, any data structure that reprents tree, JSON etc;
3) Whether to send the entire "tree" over in one shot or question by question (chunk by chunk). Chunk by chunk is in general better, and there might even be security reasons that you should not send the whole thing over in one shot...

Thanks, I'll sort it out an start a new thread
