As a quick note, I would think about:
- component view templates (make one for each question type), or new
components (as you do)
- think out a view specific data model hierarchy and parameters needed
for each template
- not mess with the PropertyBag by using viewcomponent parameters
Your current approach could be simplified if :
- populating view data according to the current question to display in
Initialize method
- calling RenderView("questiontype.singleselect") according to the
current question to display in Render method
it depends on how you want to put the code/logic (one component vs
many).
