Also this problem occurs in Unbound mode when you use FlyPostBack response such as sorting, filter, delete and etc. This problem happen because Unbound mode is not designed for doing that event. Hope this helps.</div> <div><br /></div> <div>Regards,</div> <div>Bernard</div>http://www.intersoftsolutions.com/Community/WebGrid/WebGrid-Unhandled-exception-/Mon, 24 Sep 2012 03:02:34 GMTJamesFEI<p>" Unable to communicate with servrer  " </p> <p> </p> <p>event :InitializePostBack</p> <p> </p> <p> </p>
