我环顾四周，我还没有找到一个坚实的答案，这个问题。我试图打印我的数据网格内容时，我按下一个按钮，主要问题是，我的数据网格有太多的数据，只有任何显示在屏幕上打印。我需要它来打印所有数据，如果数据不适合在当前页创建一个新的页面，并打印其余的。

下面是我使用System.Drawing.Printing打印数据网格视图的解决方案

using System.Drawing.Printing;

    private int PageCounter { get; set; } = 1;

    private int RowCounter { get; set; }

打印按钮

private void BtnPrint_Click(object sender, EventArgs e)
        {
            PrintDocument printDoc = new PrintDocument();

            IQueryable<PaperSize> paperSizes = printDoc.PrinterSettings.PaperSizes.Cast<PaperSize>().AsQueryable();
            printDoc.DefaultPageSettings.PaperSize = paperSizes.First(ps => ps.Kind == PaperKind.A4);
            printDoc.DefaultPageSettings.Margins = new Margins(0, 0, 0, 0);
            pageCounter = 1;
            printDoc.PrintPage += PrintDoc_PrintPage;
            printDoc.Print();
        }

打印方式

private void Print_Document(object sender, PrintPageEventArgs e)
        {
            if (e.Graphics == null)
                throw new Exception("Unable to find page Graphics!");

            int left = 30;
            int cellLeft = left;
            int top = 50;
            int cellWidth = 0;
            int headerHeight = 30;
            string headerName = string.Empty;
            string cellValue = string.Empty;

            Rectangle rect = new();

            int pageWidth = e.PageSettings.PaperSize.Width - 60;
            int pageHeight = e.PageSettings.PaperSize.Height - 100;

            Graphics g = e.Graphics;

            Font font = new(FontFamily, 9);
            Pen p = new(Brushes.Black, 1f);
