加載操作被卡住取得100000+條記錄wcf ria services silverlight

我打電話給一個wcf ria服務函數，它返回的記錄超過100,000條。當我調試代碼時，從該函數返回的對象需要正常的時間來加載這麼多的記錄。但是在視圖模型的加載操作的回調函數中，它會在無限時間內停留在那裏。任何人都可以請指導我這一點。加載操作被卡住取得100000+條記錄wcf ria services silverlight

請檢查下面我視圖模型的代碼...

EntityQuery<DataSetData> KPIPivotGridViewDataQuery = GridDataContext.GetPivotGridViewKPIDataQuery(KPIInfo.KPI_Id, srcTableName, HelperMethods.GetLanguageID(), dateCol, StDate, EdDate); 
      LoadOperation<DataSetData> loPivotGridViewDataQuery = GridDataContext.Load(KPIPivotGridViewDataQuery); 

      loPivotGridViewDataQuery.Completed += (sender, e) => 
      { 
       LoadOperation<DataSetData> vals = sender as LoadOperation<DataSetData>; 
       if (!vals.HasError) 
       { 
        DataSetData data = vals.Entities.FirstOrDefault(); 
        IEnumerable KPIPivotGridViewData = DynamicDataBuilder.GetDataList(data); 
        this.PivotGridViewPagedView = new RadGVPagging(KPIPivotGridViewData);//new ObservableCollection<object>(KPIPivotGridViewData.Cast<object>()); 

        this.isBusy = false; 
       } 
       else 
       { 
        this.isBusy = false; 
        //this.BIChart.IsBusy = false; 
        SilverlightMessageBox.ShowErrorDialog(vals.Error.Message, rm.GetString("msgErrorHeading", CultureInfo.CurrentUICulture)); 
        ISFLogging.AddLog(vals.Error.Message, "GetPivotGridViewData.loChartDataQuery_Completed"); 
       } 
      };
