There's a few questions on stack overflow on this topic but I'm still unclear: I know the flash engine is single threaded so when it receives an event, does it essentially break off, execute any registered event listeners (in no guaranteed order) then return to the current scope?

So I've got an ASP.NET control with a server form with a bunch of runat="server" with events defined in the markup. However none of the events are fireing when I click the buttons. The postback occurs and in the Page_Load event IsPostback is true. What should I be checking to see why the events don't fire? What are the most likely re...
I realize you can declaratively assign an event handler to a child control inside a formview by adding its attribute on the aspx page (i.e. onclick="Button_Click"), but if I wanted to do this programmatically, how would I go about it? That control isn't going to be found through FormView.FindControl in the Page's Init or Load events, so ...

Is there a way to have Firebug (o...

I found I was able to access the href, at least, by doing this...
