I need a calendar (sometimes called a scheduler) similar to google calendars that I can call from C# code behind

Functionality: - call from C# and pass 5 parms per event: ....name (example: Bob Smith) ....city (example: Naperville) ....street address (example: 123 Main) ....comment (example: NE) ....background color (example: red) - display current day and next 6 days (horizontal scrolling if necessary) - user click to add new event - new event is populated with parms in HiddenField (or some other way to pass between server code and client code) - drag any event to new day/time - edit existing event - delete existing event - upon user saving new event, pass new event's parms back to C# code This feature will integrate into an ASP.Net application I am currently building. Typical day in the life usage: 1. user clicks a button on my page 2. calendar/scheduler page popup, populated from server side 3. user clicks a time slot and a 4-hour event is created, populated with the parms passed in a HiddenField (or something similar) 4. user clicks SAVE button, then new event info is passed to server side code 5. if user drags and drops an existing event, the event info (including new day/time) is passed to server side code
