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。

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。
