我的子报表在主报表的每个单元格中显示所有结果

Question

我确实有名为 MainReport.rdlc 和 SubReport.rdlc.

的 RDLC 文件

Subreport.rdlc（很明显，充当我的子报表）。

我能够在主 Table 中显示子报表的详细信息。但问题是子报表在我的子报表中显示每一行的所有数据

我要的是这个：

但实际情况是这样的：

MainReport上的数据集查询

Select DISTINCT tblMain.ID_Num, tblMain.fldDate,Scope.Description,tblMain.Accomplishment,Rating.fldQuality, Rating.fldQuantity, Rating.fldAccuracy from tblMain 
JOIN tblScope as SCOPE on  tblMain.Scope = Scope.Id
LEFT JOIN tblRatings as Rating on tblMain.RatingRefCode = Rating.ScopeCode 
where tblMain.ID_Num = @RefNo AND fldDate between @Start and @End
Group By tblMain.ID_Num, tblMain.fldDate,Scope.Description,tblMain.Accomplishment,Rating.fldQuality, Rating.fldQuantity, Rating.fldAccuracy

这是子报表上的数据集查询

Select DISTINCT tblMain.ID_Num, tblMain.fldDate,Scope.Description,tblMain.Accomplishment from tblMain 
JOIN tblScope as SCOPE on  tblMain.Scope = Scope.Id
LEFT JOIN tblRatings as Rating on tblMain.RatingRefCode = Rating.ScopeCode 
where tblMain.ID_Num = @RefNo AND fldDate between @Start and @End
Group By tblMain.ID_Num, tblMain.fldDate,Scope.Description,tblMain.Accomplishment

Answer 1

您似乎没有设置子报表参数。

在MainReport.rdlc:

右键单击子报表 > 子报表属性 > 参数
设置名称为 ScopeParameter 且值等于数据集中范围字段的新参数（例如 [ScopeId]）

在Subreport.rdlc:

设置名称为 ScopeParameter
在您的 Tablix 或 Tablix 组中使用 [ScopeId] = @ScopeParameter

对于大量数据，使用 SubreportProcessingHandler 事件过滤子报表中的数据似乎比在 Tablix 或 Tablix Group 中设置过滤器更快。

Private Sub SubreportProcessingHandler(sender As Object, e As SubreportProcessingEventArgs)

    Dim intScope As Integer = CInt(e.Parameters.Item("ScopeParameter").Values(0))

    Dim dvYourDataView As New DataView(Me.dsYourDataset.Tables(0))
    dvYourDataView.RowFilter = "ScopeId = " & intIdScope

    e.DataSources.Add(New ReportDataSource("YourReportDataSourceName", dvYourDataView.ToTable("YourReportDataSourceName")))

End Sub

My subreport is displaying all the result in each cell in the Main Report
