Hi Kaloyan,
thanks for response,I had a RadGrid with three columns PeriodName,PeriodStartTime,PeriodEndTime ,for PeriodStartTime and periodEndtime i had took Two RadTimePickers with Time Interval 15mins and Startime ="00:09:00" (9am) EndTime= "23:00:00"(11:00pm) each in design
if we click radtimePicker in RadGrid a table will popup and shows timeperiods with 15mins intervals starting from 9:00, 9:15,9:30,9:45,10;00..so on upto 11:00pm ,if in RadGrid in a row if we enter PeriodStartTime and PeriodEndTime as 9:00 am and 10:00 am respectively
then in nextrow in periodStarTime column in radtimepicker it should notshow the time periods 9:00,9:15,9:30 ,9:45 when clicked , since the time period or time slot is alredy choosen in previous row we have to make Disable/invisible alredy enteredtime periods in radtimepicker popuplist or we have to write a message that "alredy choosen timeperiod cannot be entered", Timeperiods should be entered only once. my problem is after entering 9:00am to 10:00am in firstrow in radgrid in nextrow if we give 9:15am to 9:45 it is taking that shouldnot be, actually in PeriodName column we have "Interval" and "Lunch" for which we have to give timeduration as 15mins and 30mins respectively so we cannot put time interval in radtimepickers as 60mins its compulsion to take 15mins (for all other periods we have 60mins time duration)
