    trouble calling a webmethod

    hi

    asp.net 2.0

    The webmethod below don't get called. I'm not sure what I do wrong here. I
    think it's something to with the parameters. The GetCompletionLi st takes 2
    parameters. I don't set the value of these input parameters.

    [WebMethod]
    Car: <asp:TextBox ID="txtCar" runat="server"> </asp:TextBox>
    <cc1:AutoComple teExtender ID="AutoComplet eExtender1"
    runat="server"
    TargetControlID ="txtCar"
    ServicePath="~/Services/AutoCompleteWeb Site.asmx"
    ServiceMethod=" GetCompletionLi st"
    MinimumPrefixLe ngth="3" CompletionSetCo unt="10" >
    </cc1:AutoComplet eExtender>


    public List<stringGetC ompletionList(s tring prefix, int count)
    {
    List<stringcars = Car.GetCarsColl ection(prefix, count);
    List<stringname s = null;
    foreach (Car car in cars)
    {
    names.Add(car.U rl);
    }
    return names;
    }

    any suggestions why my code isn't executed

      The WebMethod must be declared as static...

          Re: trouble calling a webmethod

          you mean like this:

          [WebMethod]
          public static List<stringGetC ompletionList(s tring prefix, int count)
          {
          List<stringcars = Car.GetCarsColl ection(prefix, count);
          List<stringname s = null;
          foreach (Car car in cars)
          {
          names.Add(car.U rl);
          }
          return names;
          }

          I've tryed this but the code didn't execute. I wonder if that is because I
          haven't specified the values of the input parameters of the
          GetCompletionLi st... not sure how to specify them

              I am sorry i did not notice that you using it as a Service and not WebMethod
              on page.
              Then it does not need to be static.

              So you have in your project root file AutoCompleteWeb Site.asmx where you
              define this GetCompletionLi st function.

              There is a video http://www.asp.net/learn/ajax-videos/video-122.aspx on how
              to do it as well as C# code..
              Check it out.


              George.

                  Re: trouble calling a webmethod

                  Yeah I've been watching that video a few times already today. It is that
                  video I've based my code on. I still don't understand how he pass
                  paramerters to the GetCompletionLi st method. That method takes 2 parameters,
                  but I don't know where they are set.

                  any ideas how those parameters are specified?
