I tried redefining the section within the view, but that did not work since you can't have a RenderSection within a view in the first place. So, before I give up, I just wanted confirmation that one can NOT fill a section from a partial view. My workaround would be to fill a TempData value with the output from the partial views that needs to be injected into the section, and then use that in the view to fill the section.

But that just feels dirty. Hoping there is a more elegant method. I did not want to have the section OptionalContent in the view page. I just wanted it in the partial view so that I could further slice and dice what appeared where in the partial views. Not a huge deal, I just had to rearrange how the page logic was being generated.

This is quite a popular question, so I'll post my solution up. I had the same problem and although it isn't ideal, I think it actually works quite well and doesn't make the partial dependant on the view. My scenario was that an action was accessible by itself but also could be embedded into a a view - a google map. That lets me have everything separated - it's a solution that works quite well for me, others may have issues with it, but it does patch the "by design" hole.
