Question

我称之为wcf ria服务功能，它返回超过100,000条记录。当我调试代码时，从该函数返回的对象需要正常时间来加载这么多记录。但是当在视图模型的加载操作的回调函数中，它会在那里停留无限时间。谁能指导我这个。

请检查我的视图模型的代码......

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");
                }
            };

您可以传递多少数据。也许检查一下如何改变它
