The following code example ensures that a Label is visible by calling its BringToFront method. This example requires that you have a Form with a Panel named panel1, and a Label named label1.

Private Sub MakeLabelVisible()
   ' If the panel contains label1, bring it 
   ' to the front to make sure it is visible. 
   If panel1.Contains(label1) Then
      label1.BringToFront()
   End If
End Sub

private void MakeLabelVisible()
{
    /* If the panel contains label1, bring it 
       to the front to make sure it is visible. 
     */
    if (panel1.Contains(label1)) {
        label1.BringToFront();
    }
} //MakeLabelVisible
