C # using ReportViewer to generate reports

This article is a small example of report design using Microsoft's own control ReportViewer

Knowledge points involved:

• ReportViewer: Located in the Microsoft.Reporting.WinForms namespace, used primarily for report display
• Report: Reports, files ending in rdlc, visual design report templates.
• Report data: Built-in fields, parameters, images, datasets (this report mainly uses parameters, and datasets)
• ReportParameter: Instantiating a new report parameter with a name and value
• ReportDataSource: The data source of a report is associated with a DataTable object

As follows:

The relevant code is as follows:

1 /// <summary>2         ///set up a report3         /// </summary>4         Private voidSetreport ()5         {6             //First step: Clear the previous data7              This. RptView.LocalReport.DataSources.Clear ();8             //Step Two: Specify the report path9              This. RptView.LocalReport.ReportPath ="REPORT2.RDLC";Ten             //Step Three: Construct a new DataTable OneDataTable dt =NewDataTable ("DataTable1"); ADt. Columns.Add ("Name"); -Dt. Columns.Add ("score"); -Dt. Columns.Add ("Id"); theDt. Rows.Add (New Object[] {"language", the,"Y0001" }); -Dt. Rows.Add (New Object[] {"Mathematics", the,"S0001" }); -Dt. Rows.Add (New Object[] {"English", the,"E0001" }); -             //The name cannot be written incorrectly, and the dataset name in the report is the same +ReportDataSource Rdsitem =NewReportDataSource ("DataSet1", DT); -             //There can be multiple data sources here +              This. RPTVIEW.LOCALREPORT.DATASOURCES.ADD (Rdsitem); A             //Fourth step: Construct Parameters atList<reportparameter> Lstparameter =NewList<reportparameter>() { -                 NewReportParameter ("Title", This. Txttitle.text), -                 NewReportParameter ("Id", This. Txtid.text), -                 NewReportParameter ("Name", This. txtName.Text), -                 NewReportParameter (" Age", This. Txtage.text), -                 NewReportParameter ("Sex", This. Txtsex.text), in                 NewReportParameter ("Salary", This. Txtsalary.text), -                 NewReportParameter ("Depart", This. Txtdepart.text) to             }; +              This. RptView.LocalReport.SetParameters (lstparameter); -              This. Rptview.zoommode =zoommode.percent; the              This. rptview.zoompercent = -; *             //Fifth Step: Refresh the report $              This. Rptview.refreshreport ();Panax Notoginseng}
