What is the 'best' way to handle the html markup for partial views? (which are also refreshed using AJAX) The biggest issue I run into is where to place the 'container' div...

Consider having a masterpage and a partial view.
(class="" could be interchanged with id="" depending if the partial is guaranteed to be unique, however this isn't really important to the issue i think)

Masterpage:

<div id="place1" class="placeholder">
<!-- render partial -->
</div>

Partial:

<div id="partial1" class="partial">
<!-- content -->
</div>

I feel that something isn't being done right. However I cannot remove the div in the masterpage, because I need that to 'encapsulate' the response from AJAX partial updates. And also I cannot move the div in the partial to the masterpage, because that would require to move 'partial' info to the masterpage...

How do you handle this?
