RDLC子报表仅显示一行记录 [英] RDLC Subreport only display one row of record

问题描述

我有一个rdlc子报告。从数据库中检索完所有记录后，记录将显示在子报表内的Tablix中。我有10行记录，但是当它们被传递到子报表时，它只显示第一条记录。

后续记录将消失，不会显示。



我检查了tablix的属性，我没有在表达式中使用First。无论如何我可以解决这个问题吗？



以下是我将代码传递到子报告的代码。

Hi, I have a rdlc subreport. After I have retrieved all the records from database, the records will be displayed in a tablix inside the subreport. I have 10 rows of records, but when they are being passed to the subreport, it only displays the first record.
The subsequent records will disappear and would not be displayed.

I have check the properties of the tablix, I did not use "First" in the expression. Anyway I could solve this?

Below are my codes to pass the records into the subreport.

long containerHeaderId = _unitDtoList.ContainerHeaderId;
//Get the report datasources from here
ReportDataSource[] reportDataSources = new ReportDataSource[2];
reportDataSources[0] = GetUnitContainerGenealogyInquiryData(_parentUnitDtoList.DtoList[_count]
                                     ,      DataTypeConversion.StringToLong(e.Parameters[0].Values[0])
                                     , containerHeaderId);

DataSet dsTrackedBy = ToDataSet(_unitGenealogyTrackedByDetails);
reportDataSources[1] = new ReportDataSource(ConstantReference.Reports.ReportDatasourceUnitGenealogyBarcodeTrackedByDetail, dsTrackedBy.Tables[0]);

//Display the report in report viewer
foreach (var dataSource in reportDataSources)
{
     e.DataSources.Add(dataSource);
}

推荐答案

在子报表的设计上，您是否在具有唯一ID的字段上有父组？根据我的经验，您需要某种行编号（即每行数据的唯一ID）。请参阅此处的解决方案（项目符号2）：

On the design of the subreport, do you have a parent group on a field that has a unique ID? In my experience you need a "row" number (i.e. a unique ID for each row of data) of some kind. See solution (bullet 2) here:
