WebPart Initialization

WebPart Initialization

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?

partial postback, you need to use

This has gotten me further, but my solution seems to be messy. I just
don't understand why the javascript of a control doesn't get executed
automatically when it's added to the page dynamically...
