绘画到成型然后到打印机
我经常发现自己需要创建不能与 Crystal Reports 或报表查看器一起使用的自定义报表。我经常将 DataTable 组合在一起并将其转储到 DataGridView 控件中。它从来都不漂亮，而且打印也很困难。
我需要的是一个可以使用 OnPaint 事件调用的类，但直到现在我还没有坐下来编写所有的 Pen 和 Brush 命令。
绘制到屏幕和绘制到打印机都使用 Graphics 对象，因此我想构建一个类，将其传入 Graphics 对象、我的窗口边界（矩形）和一些数据（以实例的形式）我班级的），我用它来绘制表格或一张纸。
这听起来是一个很棒的概念！
当然，以前有人做过类似的事情。
有谁知道这方面的书籍、网站教程或视频吗？
如果有人想在这里为我写下所有内容，那么您将拥有更多权力 - 但我认为这工作量太大了。
I often find myself needing to create custom reports that do NOT work with Crystal Reports or Report Viewer. Often, I hack a DataTable together and dumping that into a DataGridView control. It is never pretty, and printing is difficult.
What I need is a class that I can call using the OnPaint event, but I've never sat down and written all of the Pen and Brush commands until now.
Painting to the screen and painting to a printer both use the Graphics object, so I want to build a class that I'd pass in the Graphics object, my window bounds (a Rectangle), and some data (in the form of an instance of my class) that I'd use to paint a form or a sheet of paper.
That sounds like a great concept!
Surely, someone has done something like this before.
Does anyone know of a book, a website tutorial, or video that goes into this?
If someone wants to write all that out for me here, more power to you - but I'd think that would be too much work.

如何使用 iText（免费开源 PDF 库 - http://itextpdf.com/）而不是生成 PDF 文档图形对象？然后用户就可以得到一份数字报告而不是纸质报告，更加环保一点......
How about generating a PDF document using iText (free open source PDF library - http://itextpdf.com/) instead of the graphics object? Then the user can have a digital report instead of a paper one, a little bit more environment friendly...
我最终使用 PrintPreview 对话框并将所有内容写入 OnPaint 事件中。
一旦完成，我就完全放弃了表格。一个 PrintPreview 实际上是我的客户在直接使用打印机之前查看的表单。
仅供参考：在页面上定位每个项目非常乏味。
I wound up going with a PrintPreview dialog box and writing everything in the OnPaint event.
Once that was done, I completely ditched the form. One PrintPreview that actually serves as the form for my Clients to view before going straight to the printer.
FYI: Positioning every item on the page was tedious.
