1、本文档是参考网上的资料，稍加修改，经过实际编译，可实现Winform上dataGridView控件的打印，并实现分页，下面为程序代码，仅供参考。本程序不需要在界面上添加任何打印相关控件。publicpartialclassExample:Form/打印文檔PrintDocumentpdDocument=newPrintDocument();/打印格式設置頁面PageSetupDialogdlgPageSetup=newPageSetupDialog();/打印頁面PrintDialogdlgPrint=newPrintDialog();/實例化打印預覽PrintPreviewDialogdlg

2、PrintPreview=newPrintPreviewDialog();publicExample()InitializeComponent();pdDocument.PrintPage+=newPrintPageEventHandler(OnPrintPage);/頁面設置的打印文檔設置為需要打印的文檔dlgPageSetup.Document=pdDocument;/打印界面的打印文檔設置為被打印文檔dlgPrint.Document=pdDocument;/打印預覽的打印文檔設置為被打印文檔dlgPrintPreview.Document=pdDocument;/顯示打印預覽界面，此处

3、需要添加一个打印预览的按钮/privatevoidbtnPrintView_Click(objectsender,EventArgse)dlgPrintPreview.ShowDialog();/打印设置，此处需要添加一个打印设置的按钮/privatevoidbtnPrintSetup_Click(objectsender,EventArgse)dlgPageSetup.ShowDialog();dlgPrint.ShowDialog();/IllprintDocument的PrintPage事件，实现打印功能/llllllprivatevoidOnPrintPage(objectsender

4、,PrintPageEventArgse)intiX=60;intiY=40;PrintDataGridView11.Print(dataGridView1,true,e,refiX,refiY);llllll打印，此处需添加一个打印按钮lllllllllprivatevoidbtnPrint_Click(objectsender,EventArgse)pdDocument.Print();lllIll实现DataGridView的打印类lllpublicclassPrintDataGridView11privatestaticListCellPrintList=newList();lllll

5、l打印的行数/privatestaticintprintRowCount=0;/是否要打印/privatestaticboolIsPrint=true;/设置的起始位置是否大于默认打印的边框/privatestaticboolIsRole=true;/IllX坐标/privatestaticintPoXTmp=0;lllIllY坐标lllprivatestaticintPoYTmp=0;llllll列间距lllprivatestaticintWidthTmp=0;llllll行间距lllprivatestaticintHeightTmp=0;llllll列数lllprivatestaticin

7、idView11.printRowCount=0;PrintDataGridView11.IsPrint=false;PrintDataGridView11.DataGridViewCellVsList(dataGridView,includeColumnText);/获取要打印的数据if(0=PrintDataGridView11.CellPrintList.Count)return;if(PoXeValue.MarginBounds.Left)/如果设置的起始位置大于默认打印的边框，IsRole为truePrintDataGridView11.IsRole=true;elsePrintDa

9、s.Top;elsePoX=PoXTmp;PoY=PoYTmp;while(PrintDataGridView11.printRowCounteValue.MarginBounds.Bottom)/分页HeightTmp=0;eValue.HasMorePages=true;return;重新触发OnPrintPage事件using(SolidBrushsolidBrush=newSolidBrush(CellPrint.BackColor)RectangleFrectF1=newRectangleF(PoX,PoY,CellPrint.Width,CellPrint.Height);eVal

10、ue.Graphics.FillRectangle(solidBrush,rectF1);using(Penpen=newPen(Color.Black,1)eValue.Graphics.DrawRectangle(pen,System.Drawing.Rectangle.Round(rectF1);画出单个数据的方框格子solidBrush.Color=CellPrint.ForeColor;eValue.Graphics.DrawString(CellPrint.FormattedValue,CellPrint.Font,solidBrush,newSystem.Drawing.Poin

11、t(PoX+2,PoY+3);/在方框中画出数据WidthTmp=CellPrint.Width;HeightTmp=CellPrint.Height;RowIndex=CellPrint.RowIndex;PrintDataGridView11.printRowCount+;PoY=PoY+HeightTmp;全部打印完后不再分页eValue.HasMorePages=false;PrintDataGridView11.IsPrint=true;catcheValue.HasMorePages=false;PrintDataGridView11.IsPrint=true;throw;/抛出异
