TIdIOHandlerSocket.OnBeforeBind Property

Event handler signalled prior to allocating and binding the socket handle for the IOHandler.

property OnBeforeBind: TIdNotifyEvent;

OnBeforeBind is a TNotifyEvent property that represents the event handler signalled prior to allocating and binding the socket handle for the socket-based IOHandler. 

OnBeforeBind is signalled during processing in the Open method before the Binding for the socket-based IOHandler has been allocated, initalized, and connected

Applications must assign a procedure to the event handler to allow responding to the TNotifyEvent event notification. 

Use the Owner property to access properties and methods of the TIdTCPClientCustom or descendant that owns the socket-based IOHandler.
