从DataGridColumnStyle继承，自己写，系统只提供了TextBoxStyle。
asp.net的就方便了，用个template就可以了。
刚学到的，还没研究。不过client一般不用这种专业的grid给客户操作。Top

肯定是行的，从DataGridColumnStyle继承当然可以。
我正在尝试中......Top

我已有了DataGridComboBoxColumn的源程序，是VB.net写的
我正在消化中，等我彻底弄清楚了，我会将之改写成C#, 有哪位需要的留个mail, 适当给些分就行了。Top

那个源程序是错的
第一个错误
类声明应该为：
public class TestDataGrid : System.Windows.Forms.Form
第二个错误
掉了一个(
