How to make User Control always on top ?

I have a user control and it has one janus combo box. While dropping down the combo I increased the Height of the user control to show some other controls below the combo box.
Its working fine, but the problem is : if I place the UC inside any panel or group box the User Control hiding inside the parent control. Its not always on top.

I tried in Designer that right clicking on the controls and Bring to Front
and also by code.( this.BringtoFront())

How can I bring the User control always on top..?
Please help me. Thanks!

If you truly need a "bring to front" mechanism you can switch the container of the UserControl to the FORM at run-time so that it won't be clipped by the original container. Use PointToScreen() and PointToClient() to keep the UserControl in the same position when it changes containers:

Public Class UserControl1

    Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
        Dim pt As Point = Me.PointToScreen(New Point(0, 0))
        pt = Me.ParentForm.PointToClient(pt)
        Me.ParentForm.Controls.Add(Me)
        Me.Location = pt
        Me.BringToFront()

        Me.Height = Me.Height * 2
    End Sub

End Class

AutoSize() property of the GroupBox messes up the sizing. So I simply manually increase the size of the container and set the Anchor property correctly. Now its working fine! Thanks :)
