WPF ProgressBar to call Webservice

Is it possible to show ProgressBar to show the progress of a Webservice call? I am using a web service that calls a SQL database and returns a list of requested data when requested.

Webservice code

    public List<LocationUpdate> GetAllLocationsByUserID(int UserID)
    {
        MainframeConnectionDataContext db = new MainframeConnectionDataContext();
        var validLocations = from query in db.LocationUpdates select query;
        return validLocations.ToList();
    }

Client code

    void Window1_Loaded(object sender, RoutedEventArgs e)
    {
        dg_sql_data.ItemsSource = CMainFrameConnection.GetAllLocationsByUserID(0);
    }

It currently takes about 5-10 seconds to load the data.

Any ideas?

The progress bar may not be acceptable as you apparently cannot tell how far this operation is running. It might be more appropriate to display a "loading" animation.

eg. some examples of animations you could use here http://www.ajaxload.info/



EDIT: As Dreas points out, setting IsIndeterminate is a good way to handle this.
