Question

ASP.NET。datalist控件里面插入的button和label之类的控件要如何引用？

本人C#新手求详细指教 _(:3 」∠)_
想做的是论坛的页面，用了一个datalist，想要从数据库里的用户信息Z_USER和用户回复Z_REPLY两个表分别调用头像ID和回复内容，这里还只写了一点点因为连调用都不会啊 (　´_ゝ｀)
private void dataGridBind(int user_id)
{
curPage = this.LabelPageCur.Text;
string strConn = WebConfigurationManager.ConnectionStrings["LunTanConnectionString"].ConnectionString;
SqlConnection con = new SqlConnection(strConn);
con.Open();

SqlCommand cmd = new SqlCommand("SELECT user_uname,user_sex,user_photo FROM Z_USER WHERE user_id=" + user_id.ToString(), con);
SqlDataReader reader = cmd.ExecuteReader();
if (reader.Read())
{
LabelName.Text = reader.GetString(0);
LabelSex.Text=reader.GetString(1);
if (!reader.IsDBNull(2))
Image1.ImageUrl = "~/user/touxiang.aspx?user_id=" + user_id.ToString();
else
Image1.ImageUrl = reader.GetString(1).Equals("男") ? "~/img/boy.png" : "~/img/girl.png";
}
cmd = null;
con.Close();
con = null;
}
