Im trying to handling the kendo calendar controls as like example provided KendoCalendar Calendar = ActiveBrowser.Find.ById<KendoCalendar>("startDatepicker"); Calendar.SelectDay("2017, 01, 01"); but error is returned when line KendoCalendar Calendar = ActiveBrowser.Find.ById<KendoCalendar>("startDatepicker"); is executed. Can anyone share your input on this
