I have several web parts on a page, some of which provide client-side
functionality (such as a google maps control). I've noticed that upon
first page load, everything works great. However, as soon as I invoke
a web part action such as minimizing or moving a part, those rich web
parts stop working. When I refresh the page, it works again.
It's as if something (OnInit, Render, etc) is called during page load,
but not during the web part post back. I should mention that my web
part zones are in an update panel (using .NET 3.5). Has anyone
experienced this before? Any suggestions?
