[Solved] Client side VisibleRangeStart/End

[HHalim]

How do I get the VisibleRangeStart/End from the client side? Couldn't find it in the documentation. Or if not available how to pass the current view(day/week/month) to the radwindow? I have access to the radscheduler object from OnClientAppointmentInserting/Editing event.

I need to pass these values to the radwindow for the custom advanced edit form.
This will allow for a much more efficient data load than loading all the appointments into the scheduler in the radwindow.


Thanks.

Hello Hart,

It's easy to get the VisibleRangeStart on the client-side from the RadScheduler object - 'radScheduler.get_firstDayStart()' will return exactly what you need.

Getting the End-time is a bit tricky though. You will have to calculate it manually and the duration of the 'Visible period' depends on the selected view. The currently selected view is returned by 'radScheduler.get_selectedView()'.

Since working with dates in Javascript is not as easy as one would like, the following code may seem a bit complicated, but here is an example on how to get the first day start and add 7 days if a WeekView is selected:

        function addDays(date, numberOfDays)
        {
            return new Date(date.getTime() + new Date(0).setDate(numberOfDays+1));
        }

        function showDates()
        {
            var radScheduler = $find('RadScheduler1');

            if(radScheduler.get_selectedView() == Telerik.Web.UI.SchedulerViewType.WeekView)
            {
                var startDate = radScheduler.get_firstDayStart();
                var endDate = addDays(startDate, 7);

                alert(startDate + " - " + endDate);
            }
        }

I hope this helps
