以编程方式将报告分配给我的 reportViewer

Question

我有一个报告查看器和多个报告（例如 Report1.rdlc、Report2.rdlc、ecc），我如何以编程方式在它们之间切换？

我能够分配不同的报告，但是当我执行程序时它说我需要分配数据源，我该如何实现？

编辑：到目前为止，这是我的代码：

public Report()
{
    InitializeComponent();

    this.View_StatoMagTableAdapter.Fill(this.NGStoreV2DataSet.View_StatoMag);
    this.mag2TableAdapter.Fill(this.NGStoreV2DataSet.mag2);

    this.mag2BindingSource.DataMember = "mag2";
    this.mag2BindingSource.DataSource = this.NGStoreV2DataSet;
}

private void reportViewer1_Load(object sender, EventArgs e)
{
    this.reportViewer1.Reset();

    var binding = new BindingSource();
    binding.DataSource = this.NGStoreV2DataSet.mag2;

    ReportDataSource rds = new ReportDataSource("NGStoreV2DataSet", binding);
    this.reportViewer1.LocalReport.DataSources.Clear();
    this.reportViewer1.LocalReport.DataSources.Add(rds);
    this.reportViewer1.LocalReport.ReportEmbeddedResource = "ReportViewerForm.Report2.rdlc";
    this.reportViewer1.RefreshReport();
}

新版本还是不行，当我运行程序时，它仍然要求数据来源。

我已经尝试过不同的组合，但 none 的这个有效。组合如：

var binding = new BindingSource();
binding.DataSource = this.NGStoreV2DataSet.mag2;

ReportDataSource rds = new ReportDataSource("NGStoreV2DataSet", binding);

或

ReportDataSource rds = new ReportDataSourc("NGStoreV2DataSet", this.mag2BindingSource);

编辑：我终于设法解决了这个问题！！我使用了错误的数据集（NGStoreV2DataSet 而不是 DataSet1 的报告数据集）感谢 tezzo 和 Hadi 的大力帮助 ;)

Answer 1

您需要同时设置 ReportPath 和 DataSources:

YourReportViewer.LocalReport.ReportEmbeddedResource = "ReportViewerForm.Report1.rdlc"
YourReportViewer.LocalReport.DataSources.Clear()
YourReportViewer.LocalReport.DataSources.Add(New ReportDataSource("YourTableName", yourDataTable))

Answer 2

您可以执行以下操作

var binding = new BindingSource();
binding.DataSource = yourData;
reportViewer1.Reset();
reportViewer1.LocalReport.DataSources.Add(new ReportDataSource("NGStoreV2DataSet",
                    binding));
reportViewer1.LocalReport.ReportEmbeddedResource = "ReportViewerForm.Report1.rdlc";
reportViewer1.RefreshReport();

希望对您有所帮助

/* 制作一个数据表，这是价值，清除本地很重要，您在报告中称呼数据集的名称更匹配 */

DataTable dGraph = clsDailyReports.MakeTmpDataSet.Invoke(con, SqlAtd).Tables[0];

    rpt.LocalReport.DataSources.Clear();

    Microsoft.Reporting.WebForms.ReportDataSource rptdBody = new Microsoft.Reporting.WebForms.ReportDataSource();
    rptdBody.Name = "DataSet1";
    rptdBody.Value = dBody;
    rpt.LocalReport.DataSources.Add(rptdBody);

    Microsoft.Reporting.WebForms.ReportDataSource rptdTop = new Microsoft.Reporting.WebForms.ReportDataSource();
    rptdTop.Name = "DataSet2";
    rptdTop.Value = dGraph;
    rpt.LocalReport.DataSources.Add(rptdTop);

    DataTable dDate = clsDailyReports.MakeTmpDataSet.Invoke(con, sSqlDate).Tables[0];
    Microsoft.Reporting.WebForms.ReportDataSource rptDate = new Microsoft.Reporting.WebForms.ReportDataSource();
    rptDate.Name = "DataSet3";
    rptDate.Value = dDate;
    rpt.LocalReport.DataSources.Add(rptDate);

    rpt.LocalReport.ReportPath = System.Web.HttpContext.Current.Server.MapPath(@"~\Reports\rptUnAdjustedPeriodTotals.rdlc");
    rpt.LocalReport.Refresh();

 Me.ReportViewer1.LocalReport.ReportEmbeddedResource = "ProjectName.ReportName.rdlc"

以编程方式将报告分配给我的 reportViewer

Programmatically assign report to my reportViewer

c#
