CascadingDropDown method error 500

Hi,

I've created a new project following the video found here :http://www.asp.net/learn/ajax-videos/video-77.aspx

My code is the same as in the demo, but when I run the website, I have the "method error 500" in each dropdownlist instead of the makes, models and colors...

Does anyone know what this error code means ?

Thanks for your help.

Hi Dpin,

10.5 Server Error 5xx
Response status codes beginning with the digit "5" indicate cases in which the server is aware that it has erred or is incapable of performing the request. Except when responding to a HEAD request, the server should include an entity containing an explanation of the error situation, and whether it is a temporary or permanent condition. User agents should display any included entity to the user. These response codes are applicable to any request method.

10.5.1 500 Internal Server Error
The server encountered an unexpected condition which prevented it from fulfilling the request.

To resovle the kind of problem, we suggest that you should first check whether your WebService works fine or not. Then check the Control settings. If all these are ok, but your application doesn't work properly. Please add break points to your WebService and debug it step-by-step. Here is theuseful information. Please pay special attention to my last reply.

I hope this help.

Best regards,

Jonathan
