            union all           
            select(Firstname+LastName)as consultantName from InDirectConsultant i where FirstName  like '%'+@consultantname+'%' 
            ORDER BY 1;
        End

but i have id also like this

select Consid, (FirstName+LastName)as ConsultantName from Consultant  where FirstName like '%'+@consultantname+'%'

Consid is Varchar.

Thank u hemanth

You should return a json object back from your webservivce that includes the name and the ID, and when the user selects the name, using the autocompleteselect event, grab the ID and put it in a hidden field on the page.

You will then have this ID when you post back the page.
