RDLC一些问题收集

xp下vs2010版的

1.发布时需要独立安装或Copy对应的程序集到客户端电脑
需要Copy的程序集，文件可以从c:\windows\assembly 通过dos命令复制过来。
Microsoft.ReportViewer.Common.dll                
Microsoft.ReportViewer.ProcessingObjectModel.dll
Microsoft.ReportViewer.WebForms.dll              
Microsoft.ReportViewer.WinForms.dll         
或者下载额外安装包:http://www.microsoft.com/en-us/download/details.aspx?id=6442

2.可以使用dataset, 或自定义的数据源如POCO，需要添加下数据源，在RDLC里面都是以Dataset节点显示
一个RDLC 可以定义多个数据源，添加额外数据原时，打开对应报表设计窗口，在菜单[视图]->报表数据（或者按Ctrl+alt+D)

3.固定表头问题

RDLC报表固定每页都显示表头
以XML方式打开rdlc文件
查找到
<TablixRowHierarchy>
          <TablixMembers>
            <TablixMember>
              <KeepWithGroup>After</KeepWithGroup>
              </TablixMember>
            <TablixMember>
              <Group Name="详细信息" />
            </TablixMember>
            <TablixMember>
              <KeepWithGroup>Before</KeepWithGroup>
            </TablixMember>
          </TablixMembers>
        </TablixRowHierarchy>

修改成
<TablixRowHierarchy>
          <TablixMembers>
            <TablixMember>
              <KeepWithGroup>After</KeepWithGroup>
              <RepeatOnNewPage>true</RepeatOnNewPage> 加上这句就可以了
              </TablixMember>
            <TablixMember>
              <Group Name="详细信息" />
            </TablixMember>
            <TablixMember>
              <KeepWithGroup>Before</KeepWithGroup>
            </TablixMember>
          </TablixMembers>
        </TablixRowHierarchy>

4.可以通过设置KeepTogether指定将列表不分页显示(打印视图还是要分页的)

5.相关代码

            var befMoney = 0.0m;
            if (string.IsNullOrWhiteSpace(txtCustomer.Text.Trim()))
            {
                throw new Exception("必需输入客户名称!");
            }

            //生成报表数据并绑定
            var list = new RepManager().Payable(dtpBTime.Value, dtpETime.Value.Date, txtCustomer.Text, out befMoney);
            bindingSource1.DataSource = list;
            var repDataSource = new Microsoft.Reporting.WinForms.ReportDataSource("dsRP", bindingSource1);
            reportViewer1.LocalReport.DataSources.Add(repDataSource);

            //设置报表模板
            this.reportViewer1.LocalReport.ReportEmbeddedResource = "FIStudio.WinUI.Report.RPDetail.rdlc";

            //参数设置
            var repParams = new ReportParameter[]{
                new ReportParameter("Title",string.Format("产品采购明细账--{0}",txtCustomer.Text)),
                new ReportParameter("BefMoneyTitle",string.Format("{0}前结余",dtpBTime.Text)),
                new ReportParameter("BefMoney",befMoney.ToString()),
                new ReportParameter("EndMoneyTitle",string.Format("{0}止结余",dtpETime.Text)),

                new ReportParameter("FieldA","付款"),
                new ReportParameter("FieldB","应付结余")
            };
            reportViewer1.LocalReport.SetParameters(repParams);
            //呈现
            this.reportViewer1.RefreshReport();

  6.数据源内容变更时可能有缓存 

reportViewer1.LocalReport.DataSources.Clear();调用下清空缓存

                var equipmentNo = TryParser(txtEquipmentNo.Text, "");
                var useCount = TryParser<int?>(txtUseCount.Text, 0) ;
                var service = new EquipmentServiceImpl();
                var response = service.queryBladeUseStatus(equipmentNo, useCount * 10000);

                DataTable dt = new dsBladeUseStatus.DataTable1DataTable();
                foreach (var it in response.Model)
                {
                    var row = (dsBladeUseStatus.DataTable1Row)dt.NewRow();
                    row.序号 = it.RecId;
                    row.刀片 = it.BladeNo;
                    row.设备号 = it.EquipmentNo;
                    row.维护人 = it.EditUser;
                    row["最后维护"] = GetV(it.EditTime);
                    row.使用次数 = it.UseCount.HasValue ? it.UseCount.Value.ToString() : "";
                    row.备注 = "";
                    dt.Rows.Add(row);
                }

                ReportViewer1.LocalReport.DataSources.Clear();
                var repDataSource = new Microsoft.Reporting.WebForms.ReportDataSource("ds", dt);
                ReportViewer1.LocalReport.DataSources.Add(repDataSource);

                var path = System.Web.Hosting.HostingEnvironment.MapPath("/EM/UI/BladeUseStatusQuery.rdlc");
                //设置报表模板
                this.ReportViewer1.LocalReport.ReportPath = path;

                //参数设置
                var repParams = new ReportParameter[]{ 
                new ReportParameter("QueryTime",DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss")),
                new ReportParameter("UseCount",">=" + useCount + "万次"),
                new ReportParameter("EquipmentNo",equipmentNo)
                 };
                ReportViewer1.LocalReport.SetParameters(repParams);
                this.ReportViewer1.LocalReport.DisplayName = "自动机刀片使用状态";

                //呈现
               // this.ReportViewer1.DataBind();

                ReportViewer1.LocalReport.Refresh();
            }
            catch (Exception ex)
            {
                Alert(ex.Message);
            }

WebForm中，如果不调用清空，则上面代码回导致每查询一次内参中则多一个数据集合(ds)
7.WebForm中使用强类型DataSet时，需要把DataSet放根目录下
------

8.WebForm中无法使用(vs2010--.net4.0 + xp) 自定义类为数据源，只能使用强类型的DataSet
不过绑定数据时，只要字段名称跟DataSet的Table列名对上即可,可以使用List<XXX>类型的数据绑定
另外可以建立一个类库项目,在类库项目里使用自定义类作为报表数据源，在设计完报表后需要把rdlc文件就copy到WebForm项目下
