web method error in cascadingDropdown

i am trying to use the cascading dropdownlist control, using a web service to get items from a database. the web method works fine, but i get a web method error 404 or 500. any help in solving this would be greatly appreciated.

Hi, mnyats.

I solved right now (telling the true, in this exact minute) a problem I was facing that was generating this same error message. In my case the problem was:

1 - I was trying to make cascadingDropDown to work with no service; (I guess it's possible but all the samples I got on the web says no)

2 - On the call of my service, inside my aspx page, I forgot to include the full namespace of the service;

3 - The service was with the attribute: <System.Web.Script.Services.ScriptService()> commented.

I don't know which problem are you having now, but I hope this can help...

See you!@.!

Hi,

I think Fiddler is a good choice for you to trouble shooting. Please refer to this thread: http://forums.asp.net/t/1172379.aspx
