DropDown неправильно фильтрует элемент управления ASCX

0 голосов
/ 12 февраля 2011

В моей форме есть раскрывающийся список, который должен отфильтровывать или отображать мое облако тегов для всего проекта или для конкретной итерации.Это странно, потому что я получаю разные результаты, когда выбираю определенные итерации из списка.Иногда элемент управления ascx вообще не отображается, иногда он отображает облако тегов, но оно некорректно, а иногда отображает правильное.Я понятия не имею, почему это происходит ... Заранее спасибо за вашу помощь!

Как я понял, вы используете метод filteroptions_SelectedIndexChanged для помещения выбранной итерации в сессию.А затем используйте значение из сеанса в элементе управления облаком тегов, чтобы связать правильные данные.Однако обработчики событий выполняются после событий загрузки страницы и элемента управления.Я предлагаю вам связать облако тегов в какой-то более поздний момент времени (например, Page_PreRender).

Редактировать: Я думаю, вам следует заменить метод Page_Load в файле ASCX.CS следующим фрагментом: 

    protected void Page_Load(object sender, EventArgs e)
    {
        proj_name = Request.QueryString["project"].ToString();
        proj_id = Request.QueryString["id"].ToString();
    }

    protected void Page_PreRender(object sender, EventArgs e)
    {
        if (String.IsNullOrEmpty((string)Session["iteration"]))
        {
            iteration = "0";
        }
        else
        {
            iteration = (string)Session["iteration"];
        }

        BindTagCloud();
    }
