It seems to me that in general, if I have an async event (lets say for a button click) and I change properties of another component I would often have to call RenderAsync. Otherwise, how would the button click event know which other controls to re-render? Is that correct? i.e. if I use a button click to populate the items in a listbox or something

What happens sometimes is that:

Javascript is not generated because the operations are too complex, that's why render async is a good thing, because it renders the html of a region and its children and then uses javascript to add/replace the html to the current page.

for some jquery plugins the javascript is generated, and the plugin had a general setter method, but it doesn't do anything for a given property (is the case of jqgrid column's width).

So the rule is: only user RenderAsync when strictly necessary, ie, if the code you add in an async event its not reflected in the browser.

The problem with this approach is that is programming by "trial and error"
