下面的示例演示了如何打印 GridControl 或显示它的打印预览。 要执行此操作，应使用 GridControl.Print 或 GridControl.ShowPrintPreview 方法。

Note注意

仅当 XtraPrinting 库可用时，才可以打印和预览 GridControl。 要检查是否可以打印 Grid，可以使用 GridControl.IsPrintingAvailable 属性。

在打印 Grid 时，当前的打印设置将被用于呈现 Grid。 注意，可以通过 GridView.OptionsPrint、BandedGridView.OptionsPrint 或 CardView.OptionsPrint 属性访问及修改打印设置。

        return;
    }

    // Open the Preview window.
    grid.ShowPrintPreview();
}

private void PrintGrid(GridControl grid) {
    // Check whether the GridControl can be printed.
    if (!grid.IsPrintingAvailable) {
        MessageBox.Show("The 'DevExpress.XtraPrinting' library is not found", "Error");
        return;
    }

    // Print.
    grid.Print();
}
