ReportViewer 本地报表显示单条记录

1、建一个数据集，拖两个表进入

2、建立一新的报表，引用数据集的字段，这里来自两个表

3、在页面中拖入ReportViewer控件，添加上面建立的报表

4、在后台代码的page_load事件中写入

        string orderid = "10249";
        DataSet myds = new DataSet();
        if(this.Request.QueryString["id"]!=null)
            orderid=this.Request.QueryString["id"].ToString();

        ReportParameter rptParaA = new ReportParameter("POrderID", orderid);
        ReportViewer1.LocalReport.SetParameters(new ReportParameter[] { rptParaA });
        myds = Fih.DBFramework.DbHelperSQL.ExecuteDataSet("select * from orders as a join Customers as b on a.CustomerID=b.CustomerID where a.orderid=" + orderid);

        ReportViewer1.Visible = true;
        ReportDataSource rds = new ReportDataSource("DataSet1_Orders", myds.Tables[0]);
        ReportDataSource rds1 = new ReportDataSource("DataSet1_Customers", myds.Tables[0]);
        ReportViewer1.LocalReport.DataSources.Clear();
        ReportViewer1.LocalReport.DataSources.Add(rds);
        ReportViewer1.LocalReport.DataSources.Add(rds1);
        ReportViewer1.LocalReport.Refresh();

这样就可以从地址栏中传参数显示单条记录报表
