Getting two postbacks with Firefox, not in IE...

[Josh]

I've got a radajax panel in a modal popup (ajaxcontroltoolkit). There is a button (html) in the radajaxpanel which has an onclick event which causes the panel to postback using the initAjaxRequest function specified in the API (control.ajaxRequest(args)).

This is working fine in IE but in Firefox there two postbacks occur (I have a breakpoint in the RaisePostBack event on the server, I get the same postback event twice in firefox) causing an issue with the rest of logic. Also in IE the appropriate loading panel displays whereas in Firefox it does not.

Any ideas?

I'd check the buttons "UseSubmitBehavior" is false, since you are doing the postback via a different method. I think that's the setting that needs to be flipped when you use javascript to cause the postback.
If you use the OnClick="MyJavaScript(args);"  to get things going, change it to OnClick="MyJavaScript(args);return false;" which will also stop it from causing a postback from the button.

That's it, thanks!
