最近非常频繁的使用DataGridView控件，VS提供的Winform下DataGridView的默认样式非常难看。如果做美化处理的话，需要调整的地方非常多，且该控件的很多设置属性非常的晦涩，不是很人性化。每次进行设置都煞费脑筋，并且需要设置的DataGridView控件又比较多，如果手工一个一个调整非常麻烦。如果在每个窗体里逐个一行一行的用代码来设置，会造成代码很凌乱、琐碎，因此我对DataGridView格式设置的常用项封装到一个Helper类，通过这个帮助类可以一步到位完成设置。
对DataGridView控件，我需要完成的一些基本的格式控制,包括以下一些内容:
1、标题行背景色、前景色、字体设置、平面化样式、行高
2、标题列宽度，平面化样式
3、偶数行背景色、前景色
4、奇数行背景色、前景色
5、数据行高度、字体
6、列宽度，对齐方式
7、禁止编辑、添加、删除、调整行高、列宽、排序
8、去除控件外边框
最终处理过后的风格类似如下图所示
最终我所希望的实现格式化DataGridView控件的形式是通过一行代码来实现,类似如下所示:
1 Dim mGridHelper As New CGridHelper(GridVersion, Color.FromArgb(250, 250, 250), 2 New Font("微软雅黑", 10), 30, Color.FromArgb(159, 210, 235), Color.FromArgb(0, 0, 0), 24, 3 New Font("微软雅黑", 9), 30, Color.FromArgb(250, 250, 250), Color.FromArgb(225, 225, 225), Color.FromArgb(0, 0, 0), 4 "0;80;70;595", "M;M;M;L")
其中列宽的控制通过一个字符串来设置,用分号来分隔数字,各数字依次设置对应列的宽度;列的对齐方式也类似,不过左、中、右分别用字母L/M/R表示。
接下来直接上CGridHelper类模块的代码了，代码还比较粗糙,但是满足我自己的需求就够了。
