Javascript methods for setting and getting the context keys.

JavaScript

function SetOfficeContextKey() {
           $find("<%=Auto2.ClientID %>").set_contextKey($get("<%=ddlCountryOffice.ClientID %>").value);
       }

function ClientOfficeCitySelected(sender, e) {
           debugger;
           $get("<%=hfOfficeCityCode.ClientID %>").value = e.get_value();
       }

Hi,

Removed the static keyword and it worked.

XML

[WebMethod]
   public  List<string> SearchCities(string prefixText,int count, string contextKey)
   {
       Util utility = new Util();
       List<string> CityList = new List<string>();
       CityList = utility.GetCities(prefixText,contextKey);
       return CityList;
   }
