Hi, I was wondering if somebody could shed some light on this browser behaviour: I have a form with a textarea that is submitted to to the server either via XHR (using jQuery, I've also tried with plain XMLHttpRequest just to rule jQuery out and the result is the same) or the "old fashioned" way via form submit. In both cases method="P...

So when a visitor is about to leave the site a "popup" appears asking if they'd take a quick survey. By "popup" I'm referring to a floating CSS div, not a child window (although sometimes clients don't realise this). Is it technicall...

I've managed to track down the issue in that it occurs when the value of the RadioButtonList is set in the PreLoad of a page and you are re-selecting this initial value. I have the full code of the ...
