在WinForm中打印DataGridView操作代碼

1.先創(chuàng)建一個(gè)類文件PrintDataGridView代碼如下：

2.在窗體中添加PrintDocument和PriintPreviewDialog控件，同時(shí)將PriintPreviewDialog屬性中的Document屬性設(shè)為PrintDocument的名稱，否則不能實(shí)現(xiàn)打印。在WinForm中打印DataGridView操作代碼再在窗體中添加一個(gè)按鈕，實(shí)現(xiàn)打印預(yù)覽功能。

雙擊PrintDocument其中的代碼如下：

private void PrintDocument_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
        {
            Font font = new Font("宋體", 12);
            e.Graphics.DrawString("菜單信息", font, Brushes.Red, 400, 20);
            e.Graphics.DrawString("時(shí)間" + DateTime.Now.ToLongDateString(), font, Brushes.Black, 20, 40);
            int x = 10;
            int y = 70;
            PrintDataGridView.Print(dgvInfo2, true, e, ref x, ref y);    //注意：PrintDataGridView該類位于上面所寫的業(yè)務(wù)邏輯層之中
        }

打印預(yù)覽按鈕的單擊事件中的代碼如下：

        private void btnPrint_Click(object sender, EventArgs e)
        {
            this.printPreviewDialog1.ShowDialog();
        }

至此運(yùn)行程序點(diǎn)打印就可以出現(xiàn)打印預(yù)覽
