Re: AJAX AutoCompleteExtender and Access Denied.

Hi there.

Only just saw this. The solution was to create an internal web service for the AJAX extender to communicate with and then this internal web service gets the required details from the external web service, as the AJAX control cannot call an external web service.

Hope that helps.

Thank you.

Thank you, I will give the dual web service approach a go and hopefully solve matters down that route.

You can’t make cross-domain XMLHttpRequest calls, even if the application and the WebService are on the same machine they need to be under the same folder, this is why you are getting the access denied error, this is a constrain imposed by the browser not by AJAX, you could do two things to solve this: you could move the WebService under your application´s project, or if you need the WebService to be under a different project you could add a “bridge” WebService in your application that would be called by the client and in turn would call the external WebService and return the result to the client.

Hi there.

I have a web service external to my asp.net web application ( both written in C#) and within my web application I have attached an AutoComplete on a TextBox.

As my web Service is external to the web application, I am qualifying the

ServicePath=http://localhost/MyWebService/Service.asmx,

do I also need to include a ServiceReference in the ScriptManager tag? (First question)

When I start up my web application and start to type into the TextBox I am receiving a JavaScript runtime error of "Access is denied".

Obviously I have done something daft here but I'm not sure if it is something to do with having the external web service and hence web method? Any help will be greatly appreciated please?

Thank you.
