Formatting various parts of a Calendar event in a Cal widget

[Sytematic]

For a Calendar widget, is it possible to have custom formatters for the description and name of the events?

As in; I would like to concatenate two datasource fields for the description.

Possible?

Not directly - you didn't mention your version, which may matter, but the simplest thing in this case is probably to store the string you want to show as a description in some other field on each event, and then set calendar.descriptionField to point at that other field.
