What determines if an Event is shown?

Each column uses two key properties:

• id
• start

The basic rule is that event.start must be within the specified day (column.start) and the event.resource must match the column id (column.id).

Plus:
1. If you don't specify column.id this column will show all events (regardless of event.resource value).
2. If you don't specify column.start it will use DayPilot.Calendar.startDate.

If you are using a column hierarchy, the id/start properties need to be specified on the bottom nodes (the values are not inherited from parents).

Thanks Dan. However, when I removed the column.id and resource, no events were shown at all. I had to remove the resource from the events too, to get it to work.

Thank you for your quick and detailed help!

Oh yes, you are right. Thanks for the update!

You can use column.id="*" to show all events (with or without event.resource specified).
