Validates files uploaded by the end-user.
procedure DoOnValidateValue(AValue: IActionFieldValue; var AHandled: Boolean); override;
virtual __fastcall DoOnValidateValue(IActionFieldValue AValue, Boolean AHandled);
DoOnValidateValue overrides TAdapterUpdateField's DoOnValidateValue method. If the OnValidateFile event handler is not nil (Delphi) or NULL (C++), DoOnValidateValue calls it to validate an uploaded file. DoOnValidateValues also validates that not more than one image file was uploaded and, if the required property is true, that a single file was uploaded. An exception is raised to indicate a validation error.
