Question

I don’t want to use a webservice to populate an autocomplete extender on a textbox. In this case, it’s where the user is entering country name and I don’t want to make a trip to the database every single time. I’d much rather keep a collection in session state and ‘bind’ the autocomplete to that.

Is it possible to set ServicePath and/or ServiceMethod to something in the codebehind as opposed to a webservice?

Unfortunately, there is no direct option to do that other than hacking into javascript to stop the browser from making a call to get the list.

The only other choice I can see is to create a webservice & use EnableCaching property of AutoCompleteExtender, to make sure the result of the webservice is cached on the client, thereby avoiding calls to webservice (and database in turn).

EDIT: On a second thought, I think it could be possible to mark a public static method in your page with WebMethod attribute & set the ServicePath to your aspx page.

I think it should work. But am not sure, if the framework requires it to be the webservice.
