我在winform制作了一個(gè)名為PredictOrderReport.rdlc的報(bào)表(其中的字段來自數(shù)據(jù)集DateSetPredictOrderReport)，并使用了ReportView把這個(gè)報(bào)表添加進(jìn)去了（這里顯示的數(shù)據(jù)集是DateSetPredictOrderReport）?，F(xiàn)在在ReportView的代碼中如下面所寫，可打印出來的報(bào)表除了固定下來的內(nèi)容外全是空的（固定的內(nèi)容也很模糊看不清，不知道什么原因）。請高手幫忙解釋下，代碼如下：PredictOrderReportView_Load(object sender, EventArgs e)? {? this.reportViewer1.RefreshReport();? }? ?public partial class PredictOrderReportView : Form? {? private DataTable dtPredictOrderReports;? public PredictOrderReportView(DataTable dtShipmentReport)? {? InitializeComponent();? this.dtPredictOrderReports = dtShipmentReport;? LocalReport localReport = this.reportViewer1.LocalReport；? localReport.Refresh();? localReport.ReportEmbeddedResource = "Leis.View.Operation.HawbDeparture.PredictOrderReport.rdlc";? localReport.DataSources.Add(new ReportDataSource("PredictOrderReport", dtPredictOrderReports));//這里的PredictOrderReport是報(bào)表所在的程序名稱，不知道是不是寫這個(gè)還是得寫數(shù)據(jù)集DateSetPredictOrderReport；dtPredictOrderReports是有數(shù)據(jù)內(nèi)容的，將他作為數(shù)據(jù)源給這個(gè)報(bào)表。這些疑問還請高手們幫忙解釋下，謝謝了！? localReport.Refresh();? PrintLable(localReport);? }? public void PrintLable(LocalReport lreport)? {? if (lreport == null) return;? ReportPrint reportPrint = new ReportPrint(lreport);? PrintController printController = new StandardPrintController();? reportPrint.PrintController = printController;? reportPrint.PageHeight = 90;? reportPrint.PageWidth = 110;? reportPrint.MarginLeft = 0.2;? try? {? reportPrint.Print(); ? ? }? catch (Exception e)? {? throw (e);? }? }
