VS2005已经发布好久了，但对  DataGridView  的使用,在网上的资料还比较少,DataGridView  无论是美观与功能方面都是  DataGrid  所不能比的,应该说  DataGridView  不是  DataGrid  的升级,因为  DataGridView  使用了一套全新的构建方式,引入了DataGridViewCell ,DataGridViewColumn,DataGridViewRow,等,新的概念,也使编程更容易了,它提供了  DataGridViewTextBoxColumn,DataGridViewImageColumn,DataGridLinkColumn,DataGridViewComboBoxColumn,DataGrid ViewButtonColumn,DataGridViewCheckBoxColumn,等样式列
但我们常用的远不只这些样式列,所以我不想把所有的样式列都给大家做出来,我只是想抛砖引玉通过我自己做的四个样式列来让大家掌握自定义  DataGridView  样式列的方法．由于时间仓促功能不是很完善，望大家见谅，好了大家先看看4个控件的效果．

一：DataGridViewMaskedTextBoxColumn(正则表达式样式列)

(二)DataGridViewFormat(可以获取格式的列，如N2 ,1234,11)

(三)DataGridViewTreeViewColumn(下拉列表树控件 )

(四)DataGridViewDateTimeColumn(日期选择列控件)
