{
    protected void Page_Load(object sender, EventArgs e)
    {



    }
    public RegistrationInformation RegistrationInformation
    {
        get
        {
            RegistrationInformation ri = new RegistrationInformation();
            ri.FristName = txtFirstName.Text;
            ri.LastName = txtLastName.Text;

            lblResult.Text = ri.FristName + "  " + ri.LastName + "  selected the event: " + ri.SelectedEvent;

        }
        catch
        {
            lblResult.Text = "The originating page must contain txtFirstName,txtLastName,txtEmail controls";
