微軟報表查看器使用鑽取多個數據源

我有2種數據源，AssetSummaryDataSet和AssetLatencyCompleteDataSet

「數據源實例尚未爲數據源‘AssetLatencyCompleteDataSet_fsAssetLatencyComplete’提供」

我只能選擇1個數據實例，我環顧四周，似乎應該可以爲單個報表添加其他數據源，並且它們將填充在此處顯示的報表查看器控件中。

我創建了DrillThrough處理程序，但是我仍然遇到上述錯誤。

如何將缺少的數據源實例添加到報表查看器中？

{ 
public partial class frmAssetSummaryRpt : Form 
{ 
    public frmAssetSummaryRpt() 
    { 
     InitializeComponent(); 
    } 

    private void frmAssetSummaryRpt_Load(object sender, EventArgs e) 
    { 
     // TODO: This line of code loads data into the 'assetSummaryDataSet.fsAssetRecoverySummaryByClientWO' table. You can move, or remove it, as needed. 
     this.fsAssetRecoverySummaryByClientWOTableAdapter.Fill(this.assetSummaryDataSet.fsAssetRecoverySummaryByClientWO); 


     reportViewer1.Drillthrough += new DrillthroughEventHandler(reportDrillthroughEventHandler); 

     this.reportViewer1.RefreshReport(); 


    } 
    void reportDrillthroughEventHandler(object sender, DrillthroughEventArgs e) 
    { 

     LocalReport localReport = (LocalReport)e.Report; 
     localReport.DataSources.Add(new ReportDataSource("fsAssetLatencyComplete", (object)assetLatencyCompleteDataSet.fsAssetLatencyComplete)); 
    } 

    private void button1_Click(object sender, EventArgs e) 
    { 
     frmAssetLatencyFullRpt AssetLatencyFullReport = new frmAssetLatencyFullRpt(); 
     AssetLatencyFullReport.Show(); 
    } 
}

}

您只需要以下行更改「fsAssetLatencyComplete」的

localReport.DataSources.Add(new ReportDataSource("fsAssetLatencyComplete", (object)assetLatencyCompleteDataSet.fsAssetLatencyComplete));

而是指定「AssetLatencyCompleteDataSet_fsAssetLatencyComplete」
