When adding resource columns to the Calendar view , can you specify a wildcard :
Me.DayPilotCalendar1.Columns.Add("All Events", "[some wild card symbol here]")
I've just implemented this feature for both the Calendar and the Scheduler.
If you use an asterisk ("*") as the Resource/Column value DayPilot will show all available events in that column as well.
It's available since build 6.0.2073. See also DayPilot Pro 6.0 SP1.
