datagridview 列头上加checkbox

[qinmi]

请问如何在datagridview的列头上设置一个checkbox。

请指教！谢谢！

[蛋蛋の忧伤]

兄弟，放弃吧，我这个问题都问了3礼拜了
没有人告诉

[qinmi]

难道真的没有高手吗。郁闷！

[allanli]

直接放一个CheckBox控件到列头上就可以了,用代码控制他的位置和表格数据的过滤关系
这个是最简单的办法(也许也是唯一办法了),想修改DataGridView支持这个功能,很难

想放个CHECKBOX做什么用。

        protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if(e.Row.RowType == DataControlRowType.Header)
            {
                for(int i = 1;i<Zm_list.Count+1;i++)
                {
                   e.Row.Cells[i].Text="<a herf='#'style='cursor:hand;' onclick='linkyl("+Zm_list[i-1]+")'>"+ZmName_list[i-1]+"</a>";//此处你可以添加你要的checkbox
                }
            }
        }
//还有种方法,代码如下：
                          <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"  Width="100%" AllowPaging="True" OnPageIndexChanging="GridView1_PageIndexChanging" CssClass="Table_Bgcolor" BorderStyle="None" BorderWidth="0px" CellPadding="1" CellSpacing="1" OnRowDataBound="GridView1_RowDataBound">
                        <FooterStyle HorizontalAlign="Right" />

希望对你有帮助或启示作用！这个问题启示很简单！

提醒楼上的兄弟一句。DATAGRIDVIEW和DATAGRID都分不清的人就先别发言了。

有个办法可以实现..


Public Class HeaderComboxView
Inherits DataGridView
...

end class

继承DATAGRIDVIEW.手写一个可以动态添加COMBOX的方法。.

生成控件...

关键是你这需求太恶心了。
只能用这种缺德的办法

[gyc]

Combox ？ 还是方法？

如果你要在系统上那个显示，恐怕你需要自定义控件了
如果不是必须的， 自己添加一个CheckBox列， 然后把DataGridView 的样式设置一下， 把行头设成不显示

[HimeTale]

要么换别的控件,要么自己写控件
推荐动态生成checkbox,放在行的前头

只能通过重写datagridview的列头来实现了。查了下，可参考。 http://www.cnblogs.com/gossip/archive/2008/11/22/1338868.html
