Hi Harry,

Go through the following demo link which demonstrates how to use CompareValidator for RadDatePicker. I hope this would be helpful for you.
Calendar / Validation

Also checkout the documentation on this:

hi Shinu

I got the same issue. compare validation is not working for RadDateTime picker

I resorted to doing this in javascript. I have a scheduler page set up with advanced input form, but the way the date/time are validated is the same throughout the app. This is done by getting references to the textboxes of the date/time pickers (works the same for both) - using match in this case because of UC. $find works fine when on the same page

//Get the start date
                   $telerik.$(".rsAdvDatePicker").each(function(i) {
                       if (this.id.match("StartDate") != null) {
                           startDateBox = this.id;
                           startDateBox = startDateBox.replace('_wrapper', '');
                       }
                       if (this.id.match("RadScheduler1_Form_AdvancedInsertForm1_EndDate") != null) {
                           endDateBox = this.id;
                           endDateBox = endDateBox.replace('_wrapper', '');

                       }
                       if (this.id.match("RadScheduler1_Form_AdvancedEditForm1_EndDate") != null) {
                           endDateBox = this.id;
                           endDateBox = endDateBox.replace('_wrapper', '');

                       }
                   });
                   //Get the start time
                   $telerik.$(".rsAdvTimePicker").each(function(i) {
                       if (this.id.match("StartTime") != null) {
                           startTimeBox = this.id;
                           startTimeBox = startTimeBox.replace('_wrapper', '');
                       }
                       if (this.id.match("EndTime") != null) {
                           endTimeBox = this.id;
                           endTimeBox = endTimeBox.replace('_wrapper', '');
                       }
                   });

Then use simple Date.parse to see what's up

var sDt = $find(startDateBox);
                            var sTm = $find(startTimeBox);
                            var eDt = $find(endDateBox);
                            var eTm = $find(endTimeBox);
                            //check the dates first
                            if (Date.parse(sDt.get_selectedDate() + ' ' + sTm.get_selectedDate()) > Date.parse(eDt.get_selectedDate() + ' ' + eTm.get_selectedDate())) {
                                alert("Invalid Start/End times, please make sure start time is before the end time\n" + sDt.get_selectedDate() + "\n" + eDt.get_selectedDate());
                                return false;
                            }

I did this for 2 reasons. 1 - Comparison validation wasn't working and 2 - I needed to perform client side functionality if they didn't match. Not sure if this is what you guys were looking for, but it is compare validation on a RadDateTime picker
