CascadingDropDown Help

It's EnableEventValidation. See alsoFAQ#20.

Hi,

Did you ever figure out the problem you had? I am having the same issue. Can you share your solution?

Thanks,

Michael

Hi mmai,

Yes i finally solved the problem.

First i closed Visual Studio 2005 and i uninstalled atlas and the toolkit and reinstalled it.

After reinstalling both Atlas and the toolkit, the Web.Config file was updated with plenty of entries. So my problem lied in the Web.Config file so make sure that is correct! The Method Error 500 was definetely due to the fact that the web service was not allowed to be called and return any data. Modifying and updating the Web.Config file solved this issue.

So try that.

If that doesnt work, let me know.

Hello,

try EnableEventValidation="false"

Hi guys

Wondered if you can help I have the same problem Method 500 error displayed in my dropdown box.

I have set EnableEventValidation="false and also cheeked the webconfig extensively against the webconfig in the atlas toolkit sample.

But still no luck any suggestions would be much appreciated.

Cheers

Matt

Try pagemethod instead of webservice file... I had same error until I just dropped the webservice file and put it as a pagemethod...
