如何使用业务对象绑定rdlc报表

本文关键字:rdlc 报表 绑定 对象 何使用 业务 | 更新日期: 2023-09-27 18:30:09

我有一个名为CCD_ 1的业务对象,其中我定义了三个属性,Id,Name&Flg。在我的.rdlc报告中,我应用CCD_ 2对象作为数据源,现在,我在表单的页面加载事件中编写以下代码,在其中添加报表查看器控件,并将我的报表定义为本地报表。

using (RDLC_DEMO_DBEntities objdatabase = new RDLC_DEMO_DBEntities())
        {
            lstTeamMstr = objdatabase.TeamMasters.ToList();
        }
        this.TeamMasterBindingSource.DataSource = lstTeamMstr;
        this.reportViewer1.RefreshReport();

当我使用调试检查该代码时,我在CCD_,但在windows报告中只显示六个空白行,问题出在哪里?

如何使用业务对象绑定rdlc报表

遵循以下代码:>>

string path = HttpContext.Current.Server.MapPath(Your Report path);
ReportViewer1.Reset(); //important
ReportViewer1.ProcessingMode = Microsoft.Reporting.WebForms.ProcessingMode.Local;
// Add sub report even handler if you need  
***ReportViewer1.LocalReport.SubreportProcessing += new SubreportProcessingEventHandler(MySubreportProcessingEventHandler);***
LocalReport objReport = ReportViewer1.LocalReport;
objReport.ReportPath = path;
// Add Parameter If you need 
List<ReportParameter> parameters = new List<ReportParameter>();
parameters.Add(new ReportParameter("Name", Value));
ReportViewer1.LocalReport.SetParameters(parameters);
ReportViewer1.ShowParameterPrompts = false;
ReportViewer1.ShowPromptAreaButton = false;
ReportViewer1.LocalReport.Refresh();
//Add Datasourdce
ReportDataSource reportDataSource = new ReportDataSource();
reportDataSource.Name = "Datasource Name Used due to report design";
reportDataSource.Value = DataSourceValue(Your object data-source);
objReport.DataSources.Add(reportDataSource);
objReport.Refresh();

此处子报表偶数处理程序代码

private void MySubreportProcessingEventHandler(object sender,  SubreportProcessingEventArgs e)
{
 //You can get parameter from main report 
int paramname = int.Parse(e.Parameters[0].Values[0].ToString());
//You can also add parameter in sub report if you  need like main report
//Now add sub report data source     
 e.DataSources.Add(new ReportDataSource("DataSource Name",DataSourceValue)));
}
