How to overcome the issue captcha in form post validation is always being false ?

Platform: ASP.NET MVC |
Control: Captcha

In the Captcha control with refresh handler, the CaptchaService.IsValid() method always returns false during form post validation.




To resolve this issue, use the RefreshCaptcha handler method in the controller and refresh the control only when the refresh action is performed. This will prevent the control from refreshing at the time of form post during validation. Kindly refer to the following code.

public ActionResult RefreshCaptcha(CaptchaParams parameters)
    if (parameters.CaptchaModel.ActionType == "Refresh")
          return parameters.CaptchaActions();
          return null;
