By default, the DataField(exEventStartDateTime) property is "Start" and the DataField(exEventEndDateTime) is "End". Use the DataField property to associate the exEventStartDateTime and exEventEndDateTime or exEventDuration with the fields in your data source. The DataField property must be called before calling the DataSource property. The DataSource property binds a recordset to your control. Use the DataField property to associate a property of the event with a field in the database. This way when the property is changed it is updated in the associated field. The control fires the Error event if any error occurs when handling the data source. The Syncronize method ensures that each record has associated an event, and each event has associated a record.

The following samples shows how you can bound the control to a data source:
