DataGridView 列印元件完整使用指南

本文介紹 CodePlex 開源專案 DGVPrinter，一個功能強大的 DataGridView 列印元件，支援標題、副標題、頁碼、頁首頁尾、比例欄寬等豐富設定，適合 WinForms 應用快速產出報表列印輸出。

簡單用法：基本列印

private void printToolStripButton_Click(object sender, EventArgs e)
{
    DGVPrinter printer = new DGVPrinter();
    printer.Title = "DataGridView Report";
    printer.SubTitle = "An Easy to Use DataGridView Printing Object";
    printer.SubTitleFormatFlags = StringFormatFlags.LineLimit | StringFormatFlags.NoClip;
    printer.PageNumbers = true;
    printer.PageNumberInHeader = false;
    printer.PorportionalColumns = true;
    printer.HeaderCellAlignment = StringAlignment.Near;
    printer.Footer = "Your Company Name Here";
    printer.FooterSpacing = 15;
    printer.PrintDataGridView(dataGridViewControl);
}

進階用法：儲存列印設定與預覽對話框

private void printToolStripButton_Click(object sender, EventArgs e)
{
    DGVPrinter printer = new DGVPrinter();
    printer.Title = "DataGridView Report";
    printer.SubTitle = "An Easy to Use DataGridView Printing Object";
    printer.SubTitleFormatFlags = StringFormatFlags.LineLimit | StringFormatFlags.NoClip;
    printer.PageNumbers = true;
    printer.PageNumberInHeader = false;
    printer.PorportionalColumns = true;
    printer.HeaderCellAlignment = StringAlignment.Near;
    printer.Footer = "Your Company Name Here";
    printer.FooterSpacing = 15;

    // 套用儲存的印表機與頁面設定
    if (myPrintSettings != null)
        printer.PrintDocument.PrinterSettings = myPrintSettings;
    if (myPageSettings != null)
        printer.PrintDocument.DefaultPageSettings = myPageSettings;

    // 顯示列印對話框，使用者確認後列印並儲存設定
    if (DialogResult.OK == printer.DisplayPrintDialog())
    {
        myPrintSettings = printer.PrinterSettings;
        myPageSettings = printer.PageSettings;
        printer.PrintNoDisplay(dataGridViewControl); // 不顯示對話框直接列印
    }
}
