高分求教：问在DataGrid中如何添加一列CheckBox

我的思路是:1.先给表增加一个临时字段(设为布尔值)
2.重新加载表格
不知是否有用.

这个好像是用C的编吧。
有VB.NET的吗？

这里有一个添加combobox到datagrid的实例,CheckBox也是一样的道理：
http://www.csdn.net/Develop/Read_Article.asp?Id=16434

不知道楼主是使用win还是使用web的,如果使用web很好实现

http://www.vbdotnetheaven.com/Code/Jul2003/2134.asp

<asp:TemplateColumn HeaderText="删除">
<ItemTemplate>
<asp:CheckBox id="CheckID" runat="server"></asp:CheckBox>
</ItemTemplate>
<HeaderStyle Width="6%"></HeaderStyle>
<ItemStyle HorizontalAlign="Center"></ItemStyle>
</asp:TemplateColumn>

最好的办法：

Dim grdColStyle As New DataGridBoolColumn()
With grdColStyle
.HeaderText = "锁定"
.MappingName = "blLocked"
.Width = 70
End With
