source grid 4.0.0.3 是个好东西!
介绍：
SourceGrid 是一个的完全地用C#开发的Windows窗体控件；想实现excel或者word表格的样式的话,这是最好的选择.
官方网址: http://sourceforge.net/projects/sourcegrid
下面的代码可以详细的说明如何运用这个好控件.(代码是不能直接运行的,仅做参考).
其中也包含了access数据库操作的常用方法.
还顺便加了DockPanel的演练.
DockPanel是一个可以做到vs2003工具栏,属性窗口样式的控件.
官网:http://sourceforge.net/projects/dockpanelsuite/
DockPanel suite is designed to achieve docking capability for MDI forms. It can be used to develop applications with Visual Studio .Net style user interface.
DockPanel suite is a 100%-native .Net windows forms control, written in C#
Features of DockPanel suite:
· Complex hierarchies
· Auto-hide
· Free drag-and-drop
· Nested docking
· Integration with .Net Framework and VS .Net
· Persistent to XML file
