  Hi,

  Using the examples from the MSCRM SDK and from the web, I am trying to create a Silverlight datagrid that will show Campaign Responses against for an Account in MSCRM 2011; however I get the error 'The method or operation is not implemented.' when the OrganizationRequest["Query"] = queryExpression; is being set. 

  If someone could point me into the right direction I would be most grateful!!!..

  Code below but also taken from the sdk

          public void getAccountList() {
              try
              {
                  QueryExpression queryExpression = new QueryExpression();
                 
                  //set the entity name 
                  queryExpression.EntityName = "account";
  
                  //add the attribute name which are used to fetch from the entity name.
                  queryExpression.ColumnSet = new ColumnSet();
                  queryExpression.ColumnSet.Columns = new ObservableCollection<string>(new string[] { "accountid", "name", "statecode", "statuscode", "primarycontactid", "accountnumber", "emailaddress1", "telephone1", "address1_shippingmethodcode" });
  
                  //set the order by expression, here order by expression used name to order the end result.
                  OrderExpression orderByName = new OrderExpression() { AttributeName = "name", OrderType = OrderType.Ascending };
                  queryExpression.Orders = new ObservableCollection<OrderExpression>();
                  queryExpression.Orders.Add(orderByName);
  
                  OrganizationRequest organizationRequest = new OrganizationRequest() { RequestName = "RetrieveMultiple" };
                  organizationRequest["Query"] = queryExpression;
  
                  IOrganizationService organizationService = SilverlightUtility.GetSoapService();
                  organizationService.BeginExecute(organizationRequest, new AsyncCallback(AccountList_ClickCallback), organizationService);
              }
              catch (Exception Ex)
              {
                  MessageText = string.Format("Error : {0}", Ex.Message);
              }
          }
