Question

在我的Windows应用程序中，我在PrintPriview控件中打印了多个项目，但是当项目超过25时，它不会进入下一页打印其余项目。我知道我们需要使用e.Hasmorepages = true但我无法弄清楚如何正确使用它。请帮忙。

  private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
    {
        Bitmap bmp = Properties.Resources.logo2;
        Image image = bmp;
        e.Graphics.DrawImage(image, 0, 0, image.Width, image.Height);

        e.Graphics.DrawString("Date: " + DateTime.Now.ToShortDateString(), new Font("Arial", 12, FontStyle.Regular), Brushes.Black, new Point(25, 160));
        e.Graphics.DrawString("Client Name: " + ClientNameTextBox.Text.Trim(), new Font("Arial", 12, FontStyle.Regular), Brushes.Black, new Point(25, 190));

        e.Graphics.DrawString("------------------------------------------------------------------------------------------------------------------------------------", new Font("Arial", 12, FontStyle.Regular), Brushes.Black, new Point(25, 235));
        e.Graphics.DrawString("Item Name", new Font("Arial", 12, FontStyle.Bold), Brushes.Black, new Point(30, 255));
        e.Graphics.DrawString("Quantity", new Font("Arial", 12, FontStyle.Bold), Brushes.Black, new Point(380, 255));
        e.Graphics.DrawString("Unit Price (£)", new Font("Arial", 12, FontStyle.Bold), Brushes.Black, new Point(510, 255));
        e.Graphics.DrawString("Total Price (£)", new Font("Arial", 12, FontStyle.Bold), Brushes.Black, new Point(660, 255));
        e.Graphics.DrawString("------------------------------------------------------------------------------------------------------------------------------------", new Font("Arial", 12, FontStyle.Regular), Brushes.Black, new Point(25, 270));

        int yPos = 295;

        foreach (var i in shoppingCart)
        {
            e.Graphics.DrawString(i.ItemName, new Font("Arial", 12, FontStyle.Regular), Brushes.Black, new Point(30, yPos));
            e.Graphics.DrawString(i.Quantity.ToString(), new Font("Arial", 12, FontStyle.Regular), Brushes.Black, new Point(400, yPos));
            e.Graphics.DrawString(i.UnitPrice.ToString(), new Font("Arial", 12, FontStyle.Regular), Brushes.Black, new Point(550, yPos));
            e.Graphics.DrawString(i.TotalPrice.ToString(), new Font("Arial", 12, FontStyle.Regular), Brushes.Black, new Point(700, yPos));
            yPos += 30;

        }

        e.Graphics.DrawString("------------------------------------------------------------------------------------------------------------------------------------", new Font("Arial", 12, FontStyle.Regular), Brushes.Black, new Point(25, yPos));

        e.Graphics.DrawString("Total Amount:      £" + TotalAmountTextBox.Text.Trim(), new Font("Arial", 12, FontStyle.Regular), Brushes.Black, new Point(550, yPos + 30));
        e.Graphics.DrawString("Sales Tax (16%): £" + SalesTaxTextBox.Text.Trim(), new Font("Arial", 12, FontStyle.Regular), Brushes.Black, new Point(550, yPos + 60));
        e.Graphics.DrawString("Total To Pay:       £" + TotalToPayTextBox.Text.Trim(), new Font("Arial", 12, FontStyle.Regular), Brushes.Black, new Point(550, yPos + 90));

        e.Graphics.DrawString("------------------------------------------------------------------------------------------------------------------------------------", new Font("Arial", 12, FontStyle.Regular), Brushes.Black, new Point(25, yPos + 120));

    }

提前致谢。

Answer 1

是的，你需要

a）观看y值

b）当它超过最大页面高度值时，将HasMorePages设置为true

c）离开打印页面活动。

如果需要，可以再次调用它，即当您打印或预览下一页时..

您还需要跟踪您在班级变量中打印的购物车商品;用存储/使用该项目编号的foreach循环替换for！如果return大于适合您网页的最大值，则会从事件中退出循环以及稍后的y！

还设计重复标题，但我认为你做对了！最后，另一个班级变量应该跟踪页码！

如何在c＃
