//示例代码以生成repotviewer

//sample code to generate repotviewer

rptViewer.Reset();
            rptViewer.LocalReport.DataSources.Clear();
            commonObject.command1 = new SqlCommand();
            DataTable dt = new DataTable();

//使用sp从数据库中选择详细信息以填充reportviewer

//to select details from database using sp to fill reportviewer

commonObject.command1.Parameters.AddWithValue("@CampusID", Session["CampusID"]);
           dt = commonObject.ExecuteProcedureSelect("SP_SchoolAddress");

           rptViewer.ProcessingMode = ProcessingMode.Local;
           rptViewer.LocalReport.Refresh();
           rptViewer.LocalReport.ReportPath = "Letter.rdlc";
           rptDataSource1 = new ReportDataSource("DatasetName", dt);
           rptDataSource = new ReportDataSource("Letter", dtDetails);
           rptViewer.LocalReport.DataSources.Clear();
           rptViewer.LocalReport.DataSources.Add(rptDataSource);
