Asp.net Calendar/Schedular Control

I would like a calendar control which supports? a one day view, week view and month view. It will use ajax to load appointments from an sql database. it should render in all major browsers IE 6+/Firefox 2.5+/Safari? ? 3+? ? or earlier versions where possible. the styling should be the same as found in outlook 2003 and should be fast to render. dragging and dropping of items? should only be available to? super users? (normal users should not be able to drag and drop)? and appointments must not be able to overlap (javascript prevention?) Making an appointment reoccuring must be possible. on clicking a day in the month view or week view? or time in a day view a appointment creation screen should open this screen? should use? a template. appointments should support different levels? ie show all details to some people or just that the time is not available. Appointments should show there time on the month view with the colour and description of its type ie? meeting = green block saying 5:00pm-7:00pm Meeting Offsite meeting = blue block saying 5:00pm-7:00pm Offsite? Meeting c# should be use to created the control, any version of .net is allowed. the control should be able to be customised in the designer. the control should be? similar? to <[login to view URL]># Good coding and design is financially rewarded.
