c# DataGridView问题

Question

我想在DataGridView 中的一个单元格子里加个日期控件在原来的2003的DataGrid里，声明一个DataGridTextBoxColumn d = new DataGridTextBoxColumn();
然后用   d.TextBox.Controls.Add(日期控件);这个方法就可以把日期控件弄进去了，但是问题来了，在DataGridView中的DataGridViewTextBoxColume 的类中，没有TextBox这个东西，怎么弄呢？
大家帮下我，最好代码能稍微详细点，呵呵，刚用2008，不习惯。

Answer 1

大家帮下忙，我自己也看了微软给的帮助，但是太麻烦了，要继承DataGridViewTextBoxColume类和DataGridViewTextBoxCell类，以及要实现一个接口，非常繁琐。

Answer 2

<ItemTemplate>
//加个时间控件
   </ItemTemplate>

Answer 3

这个是很复杂的一个问题，不过幸好 MSDN 里有一个简单的例子，你可以参考一下，下面是这个例子的链接。http://msdn.microsoft.com/zh-cn/library/7tas5c80.aspx这里是更多有关 DataGridView 的文章：http://msdn.microsoft.com/zh-cn/library/e0ywh3cz.aspx

Answer 4

学习学习
我有个学Java的同学，虽然不怎么喜欢c#，但他知道c#中有个DataGridView是很厉害的控件，呵呵

Answer 5

召唤星星来啊，难道没有像DataGrid控件那么简单的实现方法吗？那不是一种倒退？DataGridView没有DataGrid好用？

放的位置在 namespace 第一个大括号后面就可以了

当你单击某个单元格时，让时间控件去覆盖此单元格，然后再时间控件的valuechange里把时间值赋给单元格！当你点击的不是此单元格时让时间控件不可见！
