CustomLinkControlToField#

Qualified name: delphivcl.CustomLinkControlToField

class CustomLinkControlToField#

Bases: LinkControlToFieldDelegate

Represents the base class for linking a control to a field. The TCustomLinkControlToField class implements the functionality for linking a control to a field in a data source.

Tip: If the direction is bidirectional, then the control must support the IEditLinkObserver interface.

Active#: Embarcadero Technologies does not currently have any additional information.

AutoActivate#: Embarcadero Technologies does not currently have any additional information.

BindMethodsToEvents(prefix)#: Connects methods to component events if they are named using the following pattern: Prefix_ComponentName_EventName. Example: def handle_button1_OnClick(Sender): pass The function returns a list of tuples. Each tuple contains the name of the component, the name of the event and the method object assigned to the event. Note that the prefix parameter is optional and will default to “handle_”.
