Hello,

Our controls may operate incorrectly if the Back and Forward buttons are clicked. Please refer to the Control state is not restored if Back and Forward browser buttons are clicked article for additional details.

I suggest you set the form.autocomplete property to off to overcome the issue.

ASPx
<form id="form1" runat="server"  autocomplete="off">

It would be better to use the built-in callback functionality of ASPxPopupControl instead of ASPxCallBackPanel. To pass a callback to the server, use the ASPxClientPopupControlBase.PerformCallback event.

      Adding the autocompelete="off" does indeed fix the issue. However this will turn autocomplete off for all inputs on the page.

      Is there a way to only do this for DevExpress controls?
