ComponentOne True DataControl 8.0
Data Access Modes

A TData control can function in one of three data access modes, as determined by its DataMode property:

0 – DataSource

Data source mode is used to operate on data from an ADO Recordset. It can be a database or another source specified by the control’s data source properties (on the DataSource property page), SourceRecordset property, or DataSource and DataMember properties.  This is the default mode.

1 - MemoryArray

Memory array mode is used to store data in an internal array without relying on any external data sources.

2 - UserEvents

User events mode provides a protocol for custom data sources that cannot be implemented in data source mode or memory array mode. This mode is intended for expert users only.

At design time, you can set the DataMode property in the Visual Basic Properties window or in the DataSource property page.
