快下班了救命啊 --------------------编程问答-------------------- 我今天闲得无聊，发个给你看看吧
TextBox dl = GridView1.Rows[i].FindControl("TextBox") as TextBox;

for (int i = 0; i < GridView1.Rows.Count; i++)
{
TextBox dl = GridView1.Rows[i].FindControl("TextBox") as TextBox;
            dl.text= ds.Tables[1].Rows[i]["值"].ToString();
