Can we capture Captcha validate event on maxtimeout property

[shaili]

Hi Team,

Is is possible to figure out captcha isvalid property set to false due to maxtimeout property even though correct input provided and display different error message

Hi Shaili,

While the control does not offer an event attached to the CaptchaMaxTimeout, you can use a Button Click event to update the error text as shown below:

    protected void Button_Click(object sender, EventArgs e)
    {
        Response.Write(myRadCaptcha.IsValid);
        if (myRadCaptcha.IsValid == false)
        {
            myRadCaptcha.ErrorMessage = "session expired";
        }
    }

Hi Rumen,

Thank you for your response. But here i want to want to know how to differenciate between timeout invalid and input invalid so that i can update error message appropriately. As per the above code i don know how the captcha was invalid wether due to timeout or invalid input.Is there any way we can differenciate this.

Thank you for the clarification!

I am afraid that there isn't a suitable event or a way to distinguish the invalid input from the session timeout.

The CaptchaMaxTimeout property expires with the session. If I understand you correctly you shouldn't be able to change much when the session is invalid and distinguish the session time out or the input validity when the session is invalid, because if you make a request with an expired session, it will fail with a session error.

Perhaps the best approach is to show a message to the user prior to the session expiration: Display Session Timeout message before Session expires in ASP.Net.
