## Declaration

Source position: dbctrls.pp line 89

`public property TFieldDataLink.FieldName : string read FFieldName write SetFieldName;`

## Description

FieldName is a String property which contains the name of the field in the linked Dataset with the value for a data-aware Control. Changing the value for the property causes Field to be updated to reflect the new value. If the data link is marked as Active, the EditingChanged and Reset methods are called to trigger event handlers in the class instance.

Use the DataSource property to assign the component with the linked DataSet which contains the specified FieldName.
