|
RAD Studio VCL Reference
|
|
|
Returns the number of values associated with this adapter field.
function GetValueCount: Integer; override;
virtual __fastcall int GetValueCount();
GetValueCount implements the ValueCount property. If the EchoActionFieldValue flag is true then the result is extracted from the HTTP request. Otherwise, the OnGetValueCount event is called. GetValueCount returns zero if a value can't be found because OnGetValueCount is nil (Delphi) or NULL (C++) or the HTTP request does not contain a value for this adapter field.
