Autocomplete extender kay/valur pair

Its better to write yourself a new AutoComplete using Ajax and Handler file. because AjaxAutoExtentder need to match the return type and parameter name and type. Check the link to read more ASP.Net AutoComplete Demonstration[^]. if you need customization its better to write yourself. Style effect can add through JQuery.
