Ext.net与ReportViewer结合用.ReportViewer的rdlc绑定的数据源重新绑定,但是无法刷新

前台代码如下:

                    </div>
                </Content>
            </ext:Panel>
        </Items>
    </ext:Viewport>
    </form>
ReportViewer1的刷新是用的Ext的ajax的方式
 function search() {
            if (hd_StorageId.getValue() && txtStartTime.getValue() && txtEndTime.getValue()) {
                Ext.net.DirectMethods.searchReport(hd_StorageId.getValue(), txtStartTime.getValue(), txtEndTime.getValue(), {
                    success: function (result) {
                        resetSearch();
                    }
                    //                    failure: function (errorMsg) {
                    //                        Ext.net.Notification.show({
                    //                            iconCls: 'icon-information',
                    //                            pinEvent: 'click',
                    //                            html: errorMsg,
                    //                            title: '提示'
                    //                        });
                    //                    }
                });
            } else {
                Ext.net.Notification.show({
                    iconCls: 'icon-information',
                    pinEvent: 'click',
                    html: '请同时选择仓库、起始时间、结束时间',
                    title: '提示'
                });
            }
        }
Ext.netrdlc

Answer 1

后台方法:
   [DirectMethod]
        public void searchReport(int storageId, DateTime starttime, DateTime endtime)
        {
            #region 公共数据
            DataTable commonTable = toCommonData();            #endregion
            //所有的现存产品库存记录
            IList list = ManagerFactory.productReserveSrv.AllProductReserveRec(storageId);
            DataTable listDT = toProdReseDT(list);
            //从当前时间到查询终止时间段内 包括当前时间，不包括查询终止时间
            IList listSec = ManagerFactory.productReserveSrv.OutInRec(storageId, endtime.AddDays(1), DateTime.Now);
            DataTable listSecDT = toOutInRecDetailDT(listSec);
            //查询时间段内的出入库情况，包括两头时间点
            IList listFir = ManagerFactory.productReserveSrv.OutInRec(storageId, starttime, endtime);
            DataTable listFirDT = toOutInRecDetailDT(listFir);            foreach (DataRow dr in listDT.Rows)
            {
                //从当前时间到查询终止时间段内
                foreach (DataRow drSec in listSecDT.Rows)
                {
                    if (dr["ProductCode"].ToString() == drSec["ProductCode"].ToString() && dr["ProductBatch"].ToString() == drSec["ProductBatch"].ToString())//产品编号、批次相同
                    {
                        //objSec 4:卖 5：入
                        dr["EndQuantity"] = Convert.ToDecimal(dr["EndQuantity"]) + Convert.ToDecimal(drSec["RealQuantity"]) - Convert.ToDecimal(drSec["StorQuantity"]);
                    }
                }
                //时间段内的出入库情况
                foreach (DataRow drFir in listFirDT.Rows)
                {
                    if (dr["ProductCode"].ToString() == drFir["ProductCode"].ToString() && dr["ProductBatch"].ToString() == drFir["ProductBatch"].ToString())//产品编号、批次相同
                    {
                        dr["RealQuantity"] = drFir["RealQuantity"];
                        dr["StorQuantity"] = drFir["StorQuantity"];
                        //objSec 4:卖 5：入
                        dr["StartQuantity"] = Convert.ToDecimal(dr["EndQuantity"]) + Convert.ToDecimal(drFir["RealQuantity"]) - Convert.ToDecimal(drFir["StorQuantity"]);
                    }
                }
            }            this.ReportViewer1.Reset();
            this.ReportViewer1.ProcessingMode = ProcessingMode.Local;
            string strPath = Server.MapPath("~/") + "/View/Msec/StorageStockReport/OutInReport.rdlc";
            this.ReportViewer1.LocalReport.ReportPath = strPath;            //设置导出文件名
            this.ReportViewer1.LocalReport.DisplayName = "出入库报表";            this.ReportViewer1.LocalReport.DataSources.Clear();
            this.ReportViewer1.LocalReport.DataSources.Add(new ReportDataSource("DataSet1", listDT));
            this.ReportViewer1.LocalReport.DataSources.Add(new ReportDataSource("DataSet2", commonTable));
            this.ReportViewer1.LocalReport.Refresh();
        }
其中的listDT,commonTable都是有数据的,但是就是前台ReportViewer1的并没有刷新.而且奇怪的是,我把searchReport()放在page_load里面执行，便可以显示出数据。
我想，原因是不是这个：我ajax方式取到数据，也重新绑定了数据，但是页面并没有回发，所以造成ReportViewer1没有显示出数据。如果是这个原因的话，各位有什么号办法能解决一下?

Answer 2

自从用了一遍Ext.Net以后
对这个东西就敬而远之了
虽然他看起来很厉害

奶奶的，我的ReportViewer在Ext.Panel内就是显示不出来！
