WebForm我全部动态产生一个datagrid,怎么加入按钮列，还有怎么取得它的事件？我昨天研究了一天，没什么突破，我查找了以前的帖子，没发现

<asp:TemplateColumn>
<ItemTemplate>
<asp:Button Runat=server text="name" CommandName='<% DataBinder.Eval(Container.DataItem,"表关键字")%>'></asp:Button>
</ItemTemplate>
</asp:TemplateColumn>
然后在后台做事件就可以

大家似乎不太理解我说的意思！是这样的！
我动态产生 DataGrid mygrid = new DataGrid();
给Grid加列 mygrid.cloumns.add(mytemplatecol);//mytemplatecol是我写一个类产生的模板列；问题是我不会产生一个按钮列，像静态DataGrid的按钮列一样有编辑更新取消按钮，还有就是这些按钮事件怎样获得！那位有这方面的资料，指点一下阿！感激不尽...
有是有办法，不过我不推荐你这样做，这种方法又把我们带回asp中的老路上了。
我建议不要动态添加，不用时你隐藏就行了，动态添加的控件是不会引发回发事件的
例:产生按钮列
private void CreateButtonColumn()
{
    ButtonColumn dgc=new ButtonColumn ();
dgc.ButtonType =ButtonColumnType.LinkButton ;
dgc.CommandName="Select";
dgc.HeaderStyle .BackColor =Color.RoyalBlue ;
            dgc.Text ="选择";

dg.Columns .Add (dgc);
}
在为它加个事件
this.DataGrid1.SelectedIndexChanged += new System.EventHandler(this.DataGrid1_SelectedIndexChanged);
private void DataGrid1_SelectedIndexChanged(object sender, System.EventArgs e){}
