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。

public partial class Example : Form
{
//打印文檔
PrintDocument pdDocument = new PrintDocument();
//打印格式設置頁面
PageSetupDialog dlgPageSetup = new PageSetupDialog();
//打印頁面
PrintDialog dlgPrint = new PrintDialog();
//實例化打印預覽
PrintPreviewDialog dlgPrintPreview = new PrintPreviewDialog();
public Example()
{
InitializeComponent();
pdDocument.PrintPage += new PrintPageEventHandler(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;
}
