Indicates the help context ID for client controls and menu items.

Pascal
property HelpContext: THelpContext;
C++
__property THelpContext HelpContext;
Description

HelpContext specifies the help context for the action when it is set. This value is propagated to client controls and menu items. 

When a client control has focus and the user presses the F1 key, the control uses the value of HelpContext for this associated action to invoke the online help targeting a specific topic. The target topic is uniquely identified by a nonzero HelpContext value. Leave the HelpContext property of the client control at its default value of zero. This allows multiple controls (and multiple types of controls) to be associated with the same help topic through the one action object.

Note: HelpContext is only used when the HelpType property of this action or the client control is htInteger.
