I have a form.  On that form is a Panel called pnlData.
I dynamicly create controls on the panel data during runtime.

When a textbox gets focus, I have a "Popup" panel display a numberpad so the user can enter numbers into the field. (no keyboard)  

Here is a sample of the code that creates the 2nd panel...

   Private Sub crtNumPad(ByVal sender As TextBox)

        Dim pnlData() As Control = Me.Controls.Find("pnlData", True)

        Dim pnlNumPad As New Panel
        With pnlNumPad
            .Name = "plnNumPad"
            .Location = New System.Drawing.Point(sender.Location.X + 65, sender.Location.Y)
            .Size = New System.Drawing.Size(150, 200)
            .BackColor = Color.AliceBlue
            .Visible = True
        End With

        pnlData(0).Controls.SetChildIndex(pnlNumPad, 0)

        Dim btnTemp1 As New Button
        With btnTemp1
            .Name = "btnTemp1"
            .Location = New System.Drawing.Point(1, 1)
            .Size = New System.Drawing.Size(50, 50)
            .AutoSize = False
            .Text = "1"
        End With
        .....  more code....

End sub

When the user moves off of the field, I have the following subroutine..

    Private Sub txtItemQty_Leave(ByVal sender As System.Object, ByVal e As System.EventArgs)
        Dim pnlData() As Control = Me.Controls.Find("pnlData", True)
        For Each ctrl As Control In pnlData(0).Controls
            If ctrl.Name = "pnlNumPad" Then
            End If
    End Sub

the pnlNumPad is not removed.  

Any ideas?
