    pnlAddress.Visible = False
  End Sub

  Public Sub Button_Click (sender As System.Object, e As system.Web.UI.WebControls.CommandEventArgs)
    If e.CommandName="address" Then
      pnlName.Visible = False
      pnlPhone.Visible = False
      pnlAddress.Visible = True
    ElseIf e.CommandName = "name" Then
      pnlPhone.Visible = False
      pnlAddress.Visible = False
      pnlName.Visible = True
    ElseIF e.CommandName = "phone" Then
      pnlAddress.Visible = False
      pnlName.Visible = False
      pnlPhone.Visible = True
