问题 I've tried multiple editors and have been able to successfully find one that works 100% of the time in an updatepanel and in IE8. ckeditor works fine until a postback in which it fires a hidden error. There are posts on it but no successful resolutions. I was wondering if anyone has an example site that successfully used an editor in an updatepanel that works in all browsers. 回答1: Give http://freetextbox.com/ a try.
