True DataControl simplifies the construction of query forms by completely eliminating manual coding and the need for an in-depth understanding of SQL.

True DataControl can recognize changes to fields made by the end-user at the moment a change has been made, so you don’t have to write event procedures for all kinds of controls. No more click events in your code!

True DataControl supports filter expressions restricting the contents of the data source.

A limitation of all standard Visual Basic data sources prohibits the use of parameters in the underlying SQL statement at design time. True DataControl remedies this limitation and even allows expressions to be assigned to parameters, so they may be used without any manual coding.

You can specify the value to be assigned to a field in a new record, and even make it dependent on parameters.

True DataControl can be used to manage data in memory arrays/variables in exactly the same way as it manages data of a database origin. Just define the fields at design time, and True DataControl will create internal memory storage. This powerful feature enhances all Microsoft and third-party data-aware controls, enabling them to be used in applications and forms that are not necessarily database-related.

Validation conditions, or constraints, can be imposed upon individual fields and/or upon the record as a whole. True DataControl will automatically test the constraints when the user changes a field or posts a modified record.
