The RadCaptcha control can generate an audio code which can be enabled by setting the CaptchaImage-EnableCaptchaAudio
property to true. This will cause a link button, that retrieves the audio code, to be rendered below the CaptchaImage. Your issue is apart from setting the above mentioned property to true, you need to make some configurations in the App_Data.
Try the following steps to configure RadCaptcha to generate audio code.
- In the Solution Explorer, right click the Project and select Add | Add ASP.NET folder | App_Data.
- Locate the App_Data folders in your RadControls installation.
- Copy the App_Data\RadCaptcha to the project's \App_Data folder. The RadCaptcha folder in the RadControls installation contains the various .wav files that are required to generate the audio code.
- Enable the CaptchaAudio feature by setting the CaptchaImage - EnableCaptchaAudio property to true.
Now on running the application RadCaptcha validates the input on a post back.
