I use one date picker and two dropdown listboxes to solve to problem. start time and end time dropdowns should be 08:00 08:30 09:00 etc... add a validation rule to date picker: is in the past. add a validation rule to end time dropdown listbox: end time is less than or equal to start time. That should be fine.https://www.infopathdev.com:443/forums/thread/118548.aspxSat, 17 Mar 2018 03:22:20 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:118548Jim Li0https://www.infopathdev.com:443/forums/thread/118548.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=39&PostID=118548Hi, I find date time picker is hard to adjust. There're 2 date time pickers on the form: From and To I need From & To can only be selected 8:00 to 17:00 everyday in the future. From and To should be the same day. How to accomplish that?
