【回复按钮】是LinkButton,可以直接在LinkButton的click事件下获得该行的id或行号,
代码如下:
protected void LinkButton1_Click(object sender, EventArgs e)
{
LinkButton myLink = (LinkButton)sender;
int myIndex = ((DataListItem)(myLink.NamingContainer)).ItemIndex;//获得行号
int myid = Convert.ToInt32(DataList1.DataKeys[myIndex]);//获得id
}
