I am currently working on a project that takes advantage of some DevExpress components. Recently we ran into an issue where ASPxDateEdit caused the parent page to scroll if the control was used in an IFrame. Oddly enough this issue only happened on Chrome (and potentially other webkit browsers), but not on IE.

The only way we were able to sole this issue was to add the following css to the control

-webkit-backface-visibility: hidden;

in my case I was working with ASPXDateEdit so I added it to DevExpress’s

.dxeCalendar class.

At the time of writing this I am using DevExpress WebForms version 14.2.7 (released 22-APR-2015)
