请问怎样通过DataList删除一行记录

Question

DataList里有控件TextBox和LinkButton，LinkButton的CommandName属性为deleteResponse，我想通过点击LinkButton后执行
protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e)
    {
        if (e.CommandName == "deleteResponse")
        {
            string strconn = Convert.ToString(ConfigurationManager.AppSettings["edu"]);
            SqlConnection cn = new SqlConnection(strconn);
            cn.Open();
            Label lblTime= e.Item.FindControl("lblTime") as Label;
            string mysql = "delete from Response where ResponseTime='" + lblTime.Text.ToString() + "'";
            SqlCommand cm = new SqlCommand(mysql, cn);
            cm.ExecuteNonQuery();
            cn.Close(); 
        }
    }获取不了TextBox的内容，请问应该怎样做？？谢谢！！

 ((TextBox)(GridView1.Rows[e.NewEditIndex].Cells[2].FindControl("lblTime"))).Text;
