Refresh captcha

Question

I have config and also added Refresh captcha button/img but whole page are refresh?

You could use an HTML5 control to view your captcha images. This way you can change only the image without refreshing the whole page. I found useful information about generating captcha using .NET Graphics object in the following page: https://code.msdn.microsoft.com/Sample-of-a-simple-Captcha-f8c75c43 Note that you could generate the captcha images at the server side using REST services, and pass the generated captcha image to the server side. I am currently generating more complex captcha images using leadtools. I found the following thread that might help: http://support.leadtools.com/CS/forums/43550/ShowPost.aspx
