Thank you, Clay,
I have added reference to my web service in _submit event and then was trying to call method of my web service, but i got permission failed error. Marking form as full trust fixed the error.
Is there any other method to submit to Web Service and get return value?
I need to submit to SharePoint and to Web Service, so i am trying to do it in the code. Is there any other method to submit to Web Service in code that does not require full trust?
I will appriciate any references to the code to submit to SharePoint and Web Service. thanks
