Question

在VS 2012 C＃WinForms应用程序中，有没有人能够轻松地将物理打印机的所有行打印到DataGridView？我已经尝试过Bitmaps，但它只打印了一个截图，我看了一遍，找不到一个简单的版本，所有都已经过时了。一个好网站或任何东西的链接将非常感激。

Answer 1

快速谷歌搜索让我看到了这篇文章。它可能对你有用。这是不容易的”。您必须自己实现这些功能。但它应该得到你想要的结果。

Answer 2

最简单（也是最昂贵）的方式是购买DevExpress Controls或其他第三方工具。 - ＆GT; demo-export

DevExpress控件比标准控件强大得多，但这是一种昂贵且商业化的解决方案。

另一方面，开发人员寻找解决方案，开发和维护的时间也很昂贵。

我自2008年以来一直在使用这个，我记不起来了，但我修复了几乎所有原始源代码的问题。基本上，它使用控件生成位图图像。

由于它派生自PrintDocument，只需将此组件添加到表单中，设置DataGrid属性，然后添加打印按钮并像其他任何PrintDocument一样使用。

没有简单的方法可以在DataGridView上放置打印按钮，并打印网格视图的所有页面，因为DataGridView没有内置的导出功能。

您有以下选择：

将数据导出到其他工具（即Microsoft Excel），然后从那里打印。要了解如何执行此操作，请阅读How to export from DatagridView to Excel Sheet in C# Windows Forms。
使用具有内置导出功能的ReportViewer控件，然后打印生成的导出数据。要了解如何执行此操作，请阅读Using the WinForms ReportViewer Control
