# TDBText.DataSource

Provides access to the content displayed in the control.

## Declaration

Source position: dbctrls.pp line 311

`published property TDBText.DataSource : TDataSource read GetDataSource write SetDataSource;`

## Description

DataSource is a TDataSource property which provides access to the content for the data-aware control. DataSource is used in conjunction with the Field property to determine the dataset and field definition used when reading the value for the control.

Read and write access to the property value is redirected to the DataSource property in the internal TFieldDataLink instance used in the control. Assigning a new value to the property causes the ChangeDataSource routine to be called to apply the value to the internal TFieldDataLink instance.

Use the DataField property to specify the field name accessed in the linked dataset.
