我们用BoundColumn中的FooterText中来处理
我们使用DataGrid的属性生成器来增加FooterText,如
<asp:BoundColumn DataField="firstname" HeaderText="firstname" FooterText="<input type=text name=firstname>"></asp:BoundColumn>
最后显示的时候会在firstname列的Footer处生成一个textBox,对于事件处理，我们用
<script language="javascript">
function btAddNew()
{
__doPostBack('AddNew','');
}
</script>
来触发这个事件，其中AddNew是一个服务端控件linkbutton。

这种也会存在一些问题，比如FooterText中的控件不能绑定数据。而且也不能是WEB窗体控件. 可能也有解决办法把，我暂时不知道
