为什么动态生成的 服务器端控件，无法 使用事件。

Question

做点补充说明：设计理念是   页面上放了一个table服务器控件,还有一个按钮，当我一按下按钮，页面会回发处理后，并在table中生成一个tableRow,tableRow中有一个动态生成的linkbut控件，这个控件有个事件是myLBut_click，但我一点这个控件，怎么页面上什么都没了。 

Protected Sub butFind_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles butFind.Click



        Dim FindFileName As New FindFile
        Dim strFindPath As String = "F:\Visual Studio 2008\WebSites\FileSys\Files\SurveillanceCenterFiles"
        Dim strFindName As String = TxtFindFileName.Text
        Dim myFileSystemInfo As FileSystemInfo

        myFileSystemInfo = FindFileName.FindFile(strFindName, strFindPath)

        If myFileSystemInfo IsNot Nothing Then
            AddTableHead()
            Dim tRow As New TableRow
            Dim tCells As TableCell()
            tCells = New TableCell(4) {New TableCell, New TableCell, New TableCell, New TableCell, New TableCell}
            tCells(0).Text = myFileSystemInfo.Name
            If myFileSystemInfo.Attributes = FileAttributes.Directory Then
                tCells(1).Text = "目录"
            Else
                tCells(1).Text = "文件"
            End If

            myLBut.Text = "操作类型"
            myLBut.ID = "myLBut"
            AddHandler myLBut.Click, AddressOf myLBut_click   '为什么按下LinkButton后，页面什么都没有了。如果说一定要将代码放在page_load事件中还是算了，有没有其他方法解决

            tCells(2).Controls.Add(myLBut)
