How do I modify the AutocompleteExtender?

I want to extend the AutoCompleteExtender so that a if the search returns a large number of results, the first 10 results are displayed and the user is given some indication that there are additional matching results, with the option for them to fetch more results. Can anyone give me any pointers as to how to get started with this as I'm new to Atlas?

Hi,

I think it will be difficult to accomplish this task with the AutoCompleteExtender since it's not possibile to pass additional paramters to the auto-complete service method.

Thanks for the reply Garbin.

That seems a real shame since the nature of my application means that unless I can provide this functionality the AutoCompleteExtender is not going to be any use to me... back to the drawing board I guess!
