您当前的位置: - C# code
private void Frm_Report_Load(object sender, EventArgs e)
{
rptMental.ProcessingMode = ProcessingMode.Local;
rptMental.LocalReport.ReportEmbeddedResource = @"Record.Client.Report.chic_Report.rdlc";
rptMental.LocalReport.SubreportProcessing += new SubreportProcessingEventHandler(LocalReport_SubreportProcessing);
rptMental.LocalReport.DataSources.Add(new ReportDataSource("Ds1_chic_Report", dtchic));
this.rptMental.RefreshReport();
}
void LocalReport_SubreportProcessing(object sender, SubreportProcessingEventArgs e)
{
ReportDataSource rs = new ReportDataSource();
rs.Name = "Ds1_chicDetail_Report";
rs.Value = dtchicDetail;
e.DataSources.Add(rs);
}
上面代码 还差什么吗？
而且仔细看过 报表名 没写错。。2个 dt 也有数据
但总是显示 尚未 Ds1_chicDetail_Report 数据源 提供数据源实例
还是说 主子报表 需要些 格外设置？ 本人仅仅 只是在主报表chic_Report.rdlc中 拖了个子报表控件。。
------解决方案--------------------
- C# code
ReportDataSource rs= new ReportDataSource();
rs.Name = "Ds1_chicDetail_Report";
rs.Value = dtchicDetail;
rptMental.LocalReport.DataSources.Clear();
rptMental.LocalReport.DataSources.Add(rs);
