在单晶报表查看器中加载多个报表

Question

我将一个名为“CustomerId”的参数传递给晶体报告（'.rpt'）文件，基于其生成报告的参数。当我将此报告（'.rpt'）加载到水晶报表查看器时，它正常工作......

但我有不同的“CustomerId”。我需要根据参数生成报告并将它们加载到单个报告查看器中。 ，而不是逐个单独查看它们，我想将它们全部视为单页报告查看器。

任何人都可以告诉我如何解决这个问题....

Answer 1

您需要将CustomerID参数设置为接受多个值。同时按客户创建一个组，并在组

中的最后一个部分之后设置开始新页面

Answer 2

为每个报告创建一个报告查看器。然后报告查看者在选项卡控件上添加标签页。

        private void FormCrystalRepotViewer_Shown(object sender, EventArgs e)
    {
        ReportDocument crReport = crArrReport[0];
        crystalReportViewer.ReportSource = crReport;
        crystalReportViewer.Zoom(100);
        crystalReportViewer.PrintMode = CrystalDecisions.Windows.Forms.PrintMode.PrintToPrinter;
        tcTabControl.TabPages[0].Text = arrRaporlar.Get(0).sReportName;

        for (int i = 1; i < crArrReport.Count; i++)
        {
            crReport = crArrReport[i];
            CrystalDecisions.Windows.Forms.CrystalReportViewer crview = new CrystalDecisions.Windows.Forms.CrystalReportViewer();

            crview.ReportSource = crReport;
            crview.Zoom(100);
            crview.PrintMode = crystalReportViewer.PrintMode;
            crview.ActiveViewIndex = -1;
            crview.BorderStyle = crystalReportViewer.BorderStyle;
            crview.Cursor = crystalReportViewer.Cursor;
            crview.Dock = crystalReportViewer.Dock;
            crview.Location = crystalReportViewer.Location;
            crview.Size = crystalReportViewer.Size;
            crview.TabIndex = 0;
            crview.ToolPanelView = crystalReportViewer.ToolPanelView;
            crview.ShowParameterPanelButton = crystalReportViewer.ShowParameterPanelButton;
            crview.ShowLogo = crystalReportViewer.ShowLogo;

            crview.ReportRefresh += new CrystalDecisions.Windows.Forms.RefreshEventHandler(this.crystalReportViewer_ReportRefresh);

            TabPage page = new TabPage(arrRaporlar.Get(i).sReportName);
            tcTabControl.TabPages.Add(page);
            page.Controls.Add(crview);
            page.AutoScroll = true;
        }
    }
        private void crystalReportViewer_ReportRefresh(object source, CrystalDecisions.Windows.Forms.ViewerEventArgs e)
    {
        e.Handled = true;
        ParametreleriKontrolEt();
        crystalReportViewer.ReportSource = crArrReport[0];
        for (int i = 1; i < crArrReport.Count; i++)
        {
            CrystalDecisions.Windows.Forms.CrystalReportViewer crview = new CrystalDecisions.Windows.Forms.CrystalReportViewer();
            crview = tcTabControl.TabPages[i].Controls[0] as CrystalDecisions.Windows.Forms.CrystalReportViewer;
            crview.ReportSource = crArrReport[i];
        }
    }
