Setting Persistent Field Properties and Events
Go Up to Persistent Field Components
You can set properties and customize events for persistent field components at design time. Properties control the way a field is displayed by a data-aware component, for example, whether it can appear in a Vcl.DBGrids.TDBGrid, or whether its value can be modified. Events control what happens when data in a field is fetched, changed, set, or validated.
To set the properties of a field component or write customized event handlers for it, select the component in the Fields editor, or select it from the component list in the Object Inspector.
