It is possible that the client-side object of the RadCaptcha is still not initialized when you invoke GenerateNewImage
. Please verify that you are calling the function on the client-side event OnClientLoad
of the captcha, on Sys.Application.load
or after these events.
Nevertheless, this is a workaround that may not remove the problem entirely. Please clarify whether a gray image appears or there is no image at all when the problem occurs.
- If the image is grey, please check this help article
on the matter.
- In case the image just disappears, please provide a more detailed description of your setup and the steps for recreating the problem so that I can inspect it locally.
