Hello,
From what I see in your demo, your captcha is missing:
- using random colors for letters (very nice to see) and not only one color,
- optionally working as a page validator (could be turn on by a property) with validation group.
- auto reset after ajax request
Hope it will be in Q2 :)
Thanks

Another, important, feature that a captcha 'requires' (if you believe the guidelines of accessibility), is the ability for the control to 'speak out loud' whatever needs to be typed in.
Also, not sure if it has this already, a 'refresh', more or less a way to have it generate a new set of letters/numbers in case the user cannot read what is on his screen. Opposite of the 'speaking out loud' feature, as the user may be deaf and cannot hear the letters/numbers being said by the computer.

In reference to your questions:
CS:
- Only the color of the whole text can be changed at the moment, by setting the TextColor property of the Captcha Image. Using random colors for every character is already on our backlog for future developments.
- RadCaptcha is a page validator and when the ValidationGroup property is set, it will work as a page validator. Additionally, if there is a ValidationSummary on the page and it has the same ValidationGroup, the error message will be displayed in the summary too. New example that explores this functionality will be available for the Q2 release.
- As for the "auto reset after ajax request" can you please explain in more detail about this question?
Mike:
- RadCaptcha does not have the ability to 'speak out loud' whatever needs to be typed in. We are putting this feature on our future development list.
- The image cannot be refreshed if the user asks for new image. Again, this feature is already on our TODO list.
Kind regards,
Pero

Hi, Pero.
"The image cannot be refreshed if the user asks for new image" - Big problem if the captcha can't be read clearly. If the user completed a registration form populated with lots of info and they can't read the captcha, they will have to refresh the page and loose all the info. User's won't be happy and probably leave the site if that's case.
I was excited to see this new control, but looks like I'll have to keep my existing captcha control and wait for a better release.

I completely agree with Scott, allowing the user to re-generate another image is critical the user's ease of use.

Is it not possible to put radcaptcha in a user control, then "refresh" the captcha by dynamically removing/adding the uc to a region of the page? I have not downloaded the Beta so I have not tried this, but I have used a similar approach before.
I agree that a built in solution would be better.

Regenerating with a button seems necessary.
Still on the regenerate theme, building my own captcha I encoutered some pb with callback transactions not refreshing the captcha on the page, it would be a good idea for Telerik captcha to automatically detect RadAjaxManager and behave consistantly with callbacks: refreshing or not this is also an option here.

Hello everyone,
The initial implementation of RadCaptcha was meant to be simple and cover just the basics on purposes. We will be building upon this base and add new features. We have added your suggestions to our TODO list.

Hi,
First of all I want to thank the Telerik team for captcha control. But I have some necessary features too.
The characters that is shown in the captcha control can be defined by user.
The positions of the text box and captcha image can be set by user.
Best regards,
Kerem

Regarding your requests:
- You can choose which character set (Letters, Numbers or both) to be used for the RadCaptcha image by setting the respective value to the CaptchaImage-TextChars. You can explore this at RadCaptcha's online demos.
- Similar functionality (the user can choose individually the TextBox that should be validated) has been requested before. It is already included in our TODO list.

Hi,
The characters that is shown in the captcha control can be defined by user.
I know I can change the character set to letters, numbers or both. I actually mean specifically we have to pick some of the characters from the letters or numbers set. For example captcha should take A,B,C,D,E, 0,1, 2, 3, 4 from letter and number set and show image from these characters.
The positions of the text box and captcha image can be set by user.
I dont mean the validation of textbox actually. I mean the design of the textbox and captcha image controls. It will be very useful if we can change the positions of the controls on design time.
Thanks again,
Kerem

Hello Kerem,
First let me excuse myself for the initial misunderstanding. This feature - setting custom character sets to be used for the RadCaptcha Image text - has been requested before and it is already included in our TODO list.
Regarding the second question, I think I did not explain our plans clearly. We are planning to render only the RadCaptcha image, and set which textbox should be validated. This will enable the user to:

- Choose which label explains the user to enter the RadCaptcha code. This label can be placed anywhere on the page.

When are you planning to implement the control separation changes (having just a captcha image and pointing to a TextBox and Label)? It would be nice if we had a timeline on that so we can plan our development.

Hi Matt,
We plan to implement these new features for the next major release (Q3 2009) of the RadControls for ASP.NET AJAX, however I cannot give you specific date when the release will be available.
