ASP.NET AJAX BUG: $addHandler Can't Attach to Element Inside an IFrame in Internet Explorer

HumanCompiler — Thu, 17 Jan 2008 09:32:00 GMT

I have an iframe on my page and an html page that's loaded in it (from the same domain) and an anchor tag is clicked in the iframe I want to execute some code on my page on the client. In the Initialize method in my client object I call $addHandler and pass in the anchor tag from inside the iframe, 'click' (to attach to the onclick of the anchor tag) and my delegate. I run the code in Firefox. Everything works great. I go to Internet Explorer and run it and when I click on the anchor tag inside of the iframe I get an error of "Sys.ArgumentNullException: Value cannot be null. Parameter name: eventObject". A quick search turned up this gem of a workaround:

Bug with $addHandler applied to element in an iFrame

I hope the ASP.NET team fixes this in future versions of ASP.NET AJAX, but for now this will work.

IE 8 Exists

Ok, we all knew it existed and was being worked on, but this is the first time the IE team has talked about anything (even if there's no actual info here).

Accompanying Channel 9 thread discussing the "announcement".
