防止反码的对象类型的列表(例如.tbControl.Text = "value“)在asp中工作

Question

我使用这些属性已经有一段时间了，以前从未遇到过这个问题。我有这样的财产：

public List<AirlineTickets_DOL> lstAirlineTickets
{
    get
    {
        if (!(ViewState["lstAirlineTickets"] is List<AirlineTickets_DOL>))
        {
            ViewState["lstAirlineTickets"] = new List<AirlineTickets_DOL>();
        }

        return (List<AirlineTickets_DOL>)ViewState["lstAirlineTickets"];
    }
    set
    {
        ViewState["lstAirlineTickets"] = (List<AirlineTickets_DOL>)value;
    }
}

当数据以某种方式在OnTextChanged事件中返回时，我必须填写它，如下所示：

protected void tbFlightNumber_Book_Ticket_TextChanged(object sender, EventArgs e)
{
    AutoFillAirlineTicket(sender);
}

private void AutoFillAirlineTicket(object sender)
{
    TextBox tbFlightNumber_Book_Ticket = ((Control)sender).NamingContainer.FindControl("tbFlightNumber_Book_Ticket") as TextBox;
    TextBox tbFrom_Book_Ticket = ((Control)sender).NamingContainer.FindControl("tbFrom_Book_Ticket") as TextBox;
    TextBox tbTo_Book_Ticket = ((Control)sender).NamingContainer.FindControl("tbTo_Book_Ticket") as TextBox;

    FillFlightData(tbFlightNumber_Book_Ticket, tbDate_Book_Ticket, tbFrom_Book_Ticket, tbTo_Book_Ticket);

    UpdatePanel upAirlineTicket = ((Control)sender).NamingContainer.FindControl("upAirlineTicket") as UpdatePanel;
    upAirlineTicket.Update();

    //List<AirlineTickets_DOL> lstAirlineTickets = new List<AirlineTickets_DOL>();

    lstAirlineTickets.Add(new AirlineTickets_DOL
    {
        counter = (nCounter > 0 ? nCounter : 1),
        FlightNumber = tbFlightNumber_Book_Ticket.Text,
        From = tbFrom_Book_Ticket.Text,
        To = tbTo_Book_Ticket.Text,
    });
    nCounter++;
    ListView lstviewAirlineTickets = ((Control)sender).NamingContainer.FindControl("lstviewAirlineTickets") as ListView;
    lstviewAirlineTickets.DataSource = lstAirlineTickets;
    lstviewAirlineTickets.DataBind();
}

当我删除注释时，FillFlightData函数将填充控件(TextBoxes)，但正如我前面解释的那样，当使用该属性时，填充字段的过程不起作用，并且不会在浏览器上提供任何输出。

，如果你需要更多的解释，就告诉我。如果有人帮忙，我会很高兴的。

我找到了解决方案，将事件更改为普通的onClick事件，并确保类必须定义为Serializable。
