C# 实现Winform控件dataGridView的打印与分页

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PrintPreviewDialogdlgPrintPreview=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;}///<summary>/////顯示打印預覽界面，此处需要添加一个打印预览的按钮///</summary>///<paramname="sender"></param>///<paramname="e"></param>privatevoidbtnPrintView_Click(objectsender,EventArgse){dlgPrintPreview.ShowDialog();///<summary>///打印设置，此处需要添加一个打印设置的按钮///</summary>///<paramname="sender"></param>///<paramname="e"></param>privatevoidbtnPrintSetup_Click(objectsender,EventArgse){dlgPageSetup.ShowDialog();dlgPrint.ShowDialog();}///IllprintDocument的PrintPage事件，实现打印功能///llllllprivatevoidOnPrintPage(objectsender,PrintPageEventArgse){intiX=60;intiY=40;PrintDataGridView11.Print(dataGridView1,true,e,refiX,refiY);}lll<summary>lll打印，此处需添加一个打印按钮lll<lsummary>lll<paramname="sender"><lparam>lll<paramname="e"><lparam>privatevoidbtnPrint_Click(objectsender,EventArgse){pdDocument.Print();}}lll<summary>Ill实现DataGridView的打印类lll<lsummary>publicclassPrintDataGridView11{privatestaticList<DataGridViewCellPrint>CellPrintList=newList<DataGridViewCellPrint>();lll<summary>lll打印的行数///</summary>privatestaticintprintRowCount=0;///<summary>///是否要打印///</summary>privatestaticboolIsPrint=true;///<summary>///设置的起始位置是否大于默认打印的边框///</summary>privatestaticboolIsRole=true;///<summary>IllX坐标///</summary>privatestaticintPoXTmp=0;lll<summary>IllY坐标lll<lsummary>privatestaticintPoYTmp=0;lll<summary>lll列间距lll<lsummary>privatestaticintWidthTmp=0;lll<summary>lll行间距lll<lsummary>privatestaticintHeightTmp=0;lll<summary>lll列数lll<lsummary>privatestaticintRowIndex=0;lllIll打印DataGridView控件llllllDataGridView控件lll是否包括列标题lll为System.Drawing.Printing.PrintDocument.PrintPage事件提供数据。lll起始X坐标lll起始Y坐标lllpublicstaticvoidPrint(DataGridViewdataGridView,boolincludeColumnText,PrintPageEventArgseValue,refintPoX,refintPoY)tryif(PrintDataGridView11.IsPrint){PrintDataGridView11.printRowCount=0;PrintDataGridView11.IsPrint=false;PrintDataGridView11.DataGridViewCellVsList(dataGridView,includeColumnText);//获取要打印的数据if(0==PrintDataGridView11.CellPrintList.Count)return;if(PoX>eValue.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;elsePrintDataGridView11.IsRole=false;PrintDataGridView11.PoXTmp=PoX;PrintDataGridView11.PoYTmp=PoY;PrintDataGridView11.RowIndex=0;WidthTmp=0;HeightTmp=0;}f(0!=PrintDataGridViewll.printRowCount)//换页后确定打印的初始位置{if(IsRole)//如果设置的起始位置大于默认打印的边框,起始位置为默认打印边框{PoX=PoXTmp=eValue.MarginBounds.Left;PoY=PoYTmp=eValue.MarginBounds.Top;}else{PoX=PoXTmp;PoY=PoYTmp;}}while(PrintDataGridView11.printRowCount<PrintDataGridView11.CellPrintList.Count){DataGridViewCellPrintCellPrint=CellPrintList[PrintDataGridView11.printRowCount];f(RowIndex==CellPrint.RowIndex)//—行一行打印，CellPrint.RowIndex为datagridview1的行号PoX=PoX+WidthTmp;
