I'm trying to use either blockUI or just put in an ajax loading gif when using ajaxsubmitButton but it doesn't look like there are any properties for doing something like this while the data is loading.
I've looked at the class reference to see if something exists but I don't see any properties other than the ajax() options and html() options.
I can do my own custom call if needed but wanted to see if there is something I might be missing.
Thanks,
Ben
