如何在 C# 中打印 datagridview 的值？ [复制]

Question

我想打印 DGV 的整行。

这应该通过提取不拍照的值来完成...（如果您不明白，请在下面评论）

有什么办法可以做到吗？

仍然面临问题... https://drive.google.com/file/d/0BxqCNfHpYEJlUVg3VW5aZlpHMlk/view?usp=sharing

这是一个绝对最小的代码示例。

它打印 dgv 的所有行，包括简单的页眉和页脚..

您需要在表单中添加PrintDocument printDocument1。

也是Button cb_printPreview。

// a few variables to keep track of things across pages:
int nextPageToPrint = -1;
int linesOnPage = -1;
int linesPrinted = -1;
int maxLinesOnPage = -1;

private void printDocument1_PrintPage(object sender, 
                                      System.Drawing.Printing.PrintPageEventArgs e)
{
    // for each fresh page:
    linesOnPage = 0;
    nextPageToPrint++;

    // a short reference to the DataGridView we want to print
    DataGridView DGV = yourDataGridView;

    // I prefer mm, pick your own unit!
    e.Graphics.PageUnit = GraphicsUnit.Millimeter;

    // I want to print the columns at these fixed positions
    // the first one is the left margin, 
    // the last one a dummy at the right page margin
    int[] tabStops = new int[4] {15, 30, 100, 190};

    // I want only one column to be right-aligned:
    List<int> rightAlignedCols = new List<int>() { 1 };

    // we need to keep track of the horizontal position
    // this is also the top margin:
    float y = 35f;
    // we add a little space between the lines:
    float leading = 1.5f;
    // we will need to measure the texts we print:
    SizeF size = Size.Empty;
    // we use only one font:
    using (Font font = new Font("Consolas", 13f))
    {
        // a simple header:
        e.Graphics.DrawString("List " + printDocument1.DocumentName, 
                               font, Brushes.Black, 50, y);
        y += size.Height + 15;

        // I loop over the all rows:
        for (int row = linesPrinted; row < DGV.Rows.Count; row++)
        {

            // I print a light gray bar over every second line:
            if (row % 2 == 0) 
                e.Graphics.FillRectangle(Brushes.Gainsboro, 
                tabStops[0], y - leading / 2, e.PageBounds.Width - 25, size.Height);

            // I print all (3) columns in black, unless they're empty:
            for (int col = 0; col < DGV.ColumnCount; col++)
                if (DGV[0, row].Value != null)
                {
                    string text = DGV[col, row].FormattedValue.ToString();
                    size = e.Graphics.MeasureString(text, font, 9999);
                    float x = tabStops[col];
                    if (rightAlignedCols.Contains(col) ) 
                        x = tabStops[col + 1] - size.Width;
                    // finally we print an item:
                    e.Graphics.DrawString(text, font, Brushes.Black, x, y);
                }
           // advance to next line:
            y += size.Height + leading;
            linesOnPage++;
            linesPrinted++;
            if (linesOnPage > maxLinesOnPage)   // page is full
            {
                e.HasMorePages = true;      // more to come
                break;                      // leave the rows loop! 
            }         
       }
       e.Graphics.DrawString("Page " + nextPageToPrint, font, 
                               Brushes.Black, tabStops[3] -20, y + 15);

    }
}

private void cb_printPreview_Click(object sender, EventArgs e)
{
    PrintPreviewDialog PPVdlg = new PrintPreviewDialog();
    PPVdlg.Document = printDocument1;
    PPVdlg.ShowDialog();
}

private void printDocument1_BeginPrint(object sender, 
                                       System.Drawing.Printing.PrintEventArgs e)
{
    // create a demo title for the page header:
    printDocument1.DocumentName = " Suppliers as of  " 
                                  + DateTime.Now.ToShortDateString();
    // initial values for a print job:
    nextPageToPrint = 0;
    linesOnPage = 0;
    maxLinesOnPage = 30;
    linesPrinted = 0;
}

可以从PrintPreviewDialog触发实际打印。

还有一个PrintDialog 和一个PrintPreview 控件可提供更多选项。

显然可以添加更多东西，包括图形、多种字体等，但这应该会给你一个想法。完整的教程请参阅 WWW 和 MSDN！
