   with your wcf service, you must have a list or an observablecollection of Object X.

  try it :

  myDatagrid.itemsSource = null

  myDatagrid.itemsSource = myCollection or myList

   for example, in the link you bind the combobox with city1, city2....

  create a class City

  set property public string cityName { get; set;}

  next, use you wcf to receive a collectyion of City Object like

  ObservableCollection<City> myCollect = new  ObservableCollection<City>()

  mycollect = e.result ;

  also you can use this collection to bind with your combobox !!!

   hope this help

   Hi Kargo,

  You can try with something like this.

  Here i have modified City;provider class only.Here Service is returning data from which property is getting populated.
  

  
  

  public class CityProvider
      {
  
          public CityProvider()
          {
              ServiceReference2.WebService1SoapClient client = new SilverlightApplication2.ServiceReference2.WebService1SoapClient();
              client.HelloWorldCompleted+=new EventHandler<SilverlightApplication2.ServiceReference2.HelloWorldCompletedEventArgs>(client_HelloWorldCompleted);
  
              client.HelloWorldAsync();
          }
          void client_HelloWorldCompleted(object sender, SilverlightApplication2.ServiceReference2.HelloWorldCompletedEventArgs e)
          {
              CityList = e.Result;
          }
        
          public List<string> CityList
          {
              get;
              set;
  
          }
      }

   

  you can access resource in codebehind also   and can set its property.

  Some thing like below mentined code.

   public Page()
          {
              InitializeComponent();
             
              this.Loaded += new RoutedEventHandler(Page_Loaded);
  
       
           ServiceReference2.WebService1SoapClient client = new SilverlightApplication2.ServiceReference2.WebService1SoapClient();
           client.HelloWorldCompleted += new EventHandler<SilverlightApplication2.ServiceReference2.HelloWorldCompletedEventArgs>(client_HelloWorldCompleted);
  
           client.HelloWorldAsync();
          }
          void client_HelloWorldCompleted(object sender, SilverlightApplication2.ServiceReference2.HelloWorldCompletedEventArgs e)
          {
              CityProvider cprovider = ((CityProvider)(this.Resources["cityProvider"]));
              cprovider.CityList = e.Result;
          }

  Hey Kargo,

  ObjectX describes an example of type of your object.... In your case, I guess you have a asynchron method to retrieve an ObservableCollection (or a List) of objects  

  You must have something like ObservableCollection<typeofObject> myCollect = e.result ;

  After, you can bind with your datagrid, using ItemsSources property like myDatagrid.ItemsSource = myCollect. If you want the current row in your datagrid, create a new object (with the same type like in your ObservabeCollection) and then

  TypeOfObject myObj  = myDatagrid.SelectedItem as TypeOfObject. So you could have access to all the properties of your objet..

  For example :

  My class :

   public class Cat
      {
          public string sName { get; set; }
      }

  My WCF call :

   public void loadClient(string codends)
          {
              srFormation.Service1Client myService = new nSLFormationWeb.srFormation.Service1Client();
              myService.GetCatCompleted += new EventHandler<nSLFormationWeb.srFormation.GetCatCompletedEventArgs>(myService_GetCatCompleted);
              myService.GetCatAsync();
          } 

  void myService_GetCatCompleted(object sender, nSLFormationWeb.srFormation.GetAllClientFor1FormCompletedEventArgs e)
          {
           
                  myCollect = new ObservableCollection<Cat>();
                  myCollect = e.Result;
                  dgCat.ItemsSource = null;
                  dgCat.ItemsSource = myCollect;
          }

  private void GetName()

  { Cat myCat = dgCat.SelectedItem as Cat;

  MessageBox.Show("Name : "+myCat.sName); //if you want to display the name of the cat

  Hope this help you !!
