public void CTRL1_Clicked(object sender, ClickedEventArgs e)
{
   string strExpirationDate = DateTime.Today.AddDays(2).ToString();
   DateTime dtExpirationDate = DateTime.Parse(strExpirationDate);

   this.Permission.UserPermissions.Add("someone@example.com",
      dtExpirationDate);
}

Public Sub CTRL1_Clicked(ByVal sender As Object, _
   ByVal e As ClickedEventArgs)
   Dim strExpirationDate As String = _
      DateTime.Today.AddDays(2).ToString()
   dtExpirationDate As DateTime = DateTime.Parse(strExpirationDate)

   Me.Permission.UserPermissions.Add("someone@example.com", _
      dtExpirationDate)
