Responsive View?

This does NOT work. It still shows as 3 months accross on my phone....

            //DeviceScreenDimensions screenSize = Detector.GetScreenDimensions(Request.UserAgent);
            //if (screenSize.Width > 0 && screenSize.Width <= 500)
            //    radCalendar.MultiViewColumns = 1;
            //else if (screenSize.Width > 500 && screenSize.Width < 1000)
            //    radCalendar.MultiViewColumns = 2;
            //else
            //    radCalendar.MultiViewColumns = 3;

This does seem to work....

            DeviceScreenSize screenSize = Detector.GetScreenSize(Request.UserAgent);
            if (screenSize == DeviceScreenSize.Small)
                radCalendar.MultiViewColumns = 1;
            else if (screenSize == DeviceScreenSize.Medium)           
                radCalendar.MultiViewColumns = 2;
            else
                radCalendar.MultiViewColumns = 3;
