Returns the value of this adapter field as a variant.
function ImplGetValue: Variant; override;
virtual __fastcall Variant ImplGetValue();
ImplGetValue returns the value of this adapter field as a variant. First, the access rights defined for this adapter field are validated against the rights of the end-user. If the end-user does not have rights to view this field, an exception is raised. If the EchoActionFieldValue property is true, then the value entered by end-user is returned. If the EchoActionFieldValue property is false then the OnGetValue event handler is called to retrieve the value of the adapter field.
