I am trying to populate my RadComboBox from a web service. I have a simple example working in a separate project, but when I paste the same code into my project (same control, same web service), the web service is not called and the combo box is not populated.
What could I be doing that would prevent the web service from being called?

Hi Rick,
Set the path as WebService.asmx instead of WebService.cs and check whether its working fine. I tried the code below and its working fine for me.
Here is the ASPX:

Shinu,
Yes, that was one problem.
The other problem, in my actual application, was that the "OnClientFocus" property was set to an invalid value. This was apparently causing a script error that prevented the web service from being called on the page. It also prevented the ItemsRequested event from firing, which is why I could not get the RadComboBox to work using either interface. Now that I have removed that problem and also fixed the path as you suggest, the code is working.
Thanks.
Rick.
