อยากทราบวิธีดึงข้อมูลจาก Label ในหน้า Master Page ไปแสดงใน Label ของ Web From หน่อยครับ

Sub Page_Load()
    Dim mpContentPlaceHolder As ContentPlaceHolder
    Dim mpTextBox As TextBox
    mpContentPlaceHolder = _
        CType(Master.FindControl("ContentPlaceHolder1"), _
        ContentPlaceHolder)
    If Not mpContentPlaceHolder Is Nothing Then
        mpTextBox = CType(mpContentPlaceHolder. _
            FindControl("TextBox1"), TextBox)
        If Not mpTextBox Is Nothing Then
            mpTextBox.Text = "TextBox found!"
        End If
    End If

    ' Gets a reference to a Label control not in a 
    ' ContentPlaceHolder
    Dim mpLabel As Label
    mpLabel = CType(Master.FindControl("masterPageLabel"), Label)
    If Not mpLabel Is Nothing Then
        Label1.Text = "Master page label = " + mpLabel.Text
    End If
End Sub
