ASP.NET Captcha control support for ValidationGroups and ValidationSummary

If you have used various Captcha controls for ASP.NET in the past, you may have run into roadblocks preventing the Captcha control from being fully usable.

One of the major roadblocks with nearly every ASP.NET Captcha control on the market today is that they do not have integrated support for the ASP.NET Validation Controls, thus making it it difficult to fully integrate validation logic with these Captcha controls.

Well, fortunately, 2 vendors now have Validation support for their Captcha controls!

1. Telerik RadCaptcha: http://demos.telerik.com/aspnet-ajax/captcha/examples/validationsummary/defaultcs.aspx
2. Obout Captcha: http://www.obout.com/Obout.Ajax.UI/Captcha/examples/ValidationSummary.aspx

I have used the Telerik RadCaptcha control for several years and the Validation support is an extremely new and recent addition to the RadCaptcha control.  Therefore, if you are currently using the RadCaptcha control, you will want to make sure that you update to the latest version of the Telerik ASP.NET for AJAX Controls.

If you have not used the Obout controls in the past, you will be glad to know that they are FREE!  You can download the full suite of available controls from here: http://www.obout.com/inc/download.aspx
