动态linkbutton无法触发事件

   在master中有个Table，因为菜单是动态的，所以要动态生成linkButton,但是这个生成后linkButton的Command
    事件应该如何邦定呢。下边代码是触发的
                      TdSubMenu2_2.Attributes.Add("onmouseover", strOnmouseover)
                        TdSubMenu2_2.Attributes.Add("onmouseout", strOnmouseout)
                        Dim linkButton As LinkButton = Nothing
                        If SubMuen Is Nothing Then
                            linkButton = New LinkButton()
                            subMenuCount = subMenuCount + 1
                            linkButton.ID = "Lbtn" & i & j
                            '子菜单的内容
                            linkButton.Text = dataRowSubmenu(j).Item("SubMenuName").ToString()
                            '子菜单的连接地址
                            linkButton.PostBackUrl = dataRowSubmenu(j).Item("SubMenuUrl").ToString()
                            linkButton.CommandName = "Lbtn"
                            linkButton.CommandArgument = i & j
                            AddHandler linkButton.Command, AddressOf Select_Command
                            hastable.Add(linkButton.ID, linkButton)
                        Else
                            linkButton = CType(SubMuen.Item("Lbtn" & i & j), LinkButton)
                        End If
                        TdSubMenu2_2.Controls.Add(linkButton)
                        TrSubMenu2.Cells.Add(TdSubMenu2_2) --------------------编程问答-------------------- 又来一个同样问题。。请在Page_Init或者之前的页面事件之前动态添加控件。

补充：.NET技术 ,  VB.NET
