Here is a possible realization of your requirement:

Setup the timetable view with the required number of locations and days, enable grouping, and so on. Handle the TimetableColumnHeaderClick event. This event is fired when the user clicks on any of the Timetable column headers. Since at the moment you cannot distinguish whether the user clicked on the date header or on a location header, you can use the Calendar.GetLocationAt method with the center of the DateEventArgs.Bounds property to retrieve a reference to the location associated with the clicked header. If this is null, the user clicked on the date header.

To switch the view to show the items of the clicked location, do the following:

calendar.BeginInit();
calendar.Locations.Clear();
calendar.Locations.Add(location);
calendar.GroupType = GroupType.FilterByLocations;
calendar.EndInit(); 

where location is the reference of the location whose items to display. Also make sure you specify the required number of display dates through the TimetableSettings.Dates and TimetableSettings.VisibleColumns properties.

To return back to the grouped view, you ca use an external button on your interface, or another click on any of the timetable headers. Simply revert the value of the GroupType property and the previously selected locations.

Set the VisibleColumns property of the Calendar.TimetableSettings object to the number of columns you would like to have visible at once (lets say 5).

Hope that helps.

You can do this easily by making the following modifications:

1. Instead of specifying FilterByLocation when a location header is hit, replace it with the following line:

calendar.TimetableSettings.ReverseGrouping = State.Enabled; 

This will effectively reverse the headers position by placing the location header above the date headers.

2. When you turn back to group view, disable reversed grouping, by setting the value of the property to Disabled.

Can't you just check whether the Schedule.Items collection already contains an appointment with specific id before attempting to add it?
