string str_status = "update lab_course set Cou_status=1 where Cou_num='" + Counum + "'";
Comm1 com_status = new Comm1();
com_status.ENQ(str_status);
Response.Write("<script>window.alert('学期课程添加成功!')</script>");
}
else

string str_status = "update lab_course set Cou_status=0 where Cou_num='" + Counum + "'";
Comm1 com_status = new Comm1();
com_status.ENQ(str_status);
}
}
}
}

我想获取<asp:BoundColumn DataField="Cou_num" Visible="False"></asp:BoundColumn>中Cou_num的值,怎么实现啊?

把button放到grid里面绑定是可以取到的

e.Item.Cells(i).Text i就是你要的列的索引号

放在外面的话 2005可以取selectedcells(0).text

e.Item.Cells(i).Text

这里的不应该是"()"，应该是“[]”

恩知道了,我的button是放外面的谢谢大家
selectedcells(0).text可以直接用吗?
例如:int Counum = int.Parse(selectedcells(0).text);
