哪个事件对会话的变量有价值？ [英] Which event takes value the session's variables?

问题描述

我在转发器控件的ItemDataBound事件中调用一个使用用户会话值的对象，但是我得到错误，似乎无法创建对象，并且当我在后续事件中使用同一个对象时在加载时，我没有问题，我需要知道何时开始会话的变量存在？





代码是如下：

I'm invoking in the ItemDataBound event of repeater control an object that uses the value of the user's session, but I get error, it seems that the object can not to be created and when I use this same object in subsequent events at load, I haven't problem, I need to know when to start the session's variables at exist?.


the code is the follow:

protected void repDias_OnItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
	DateTime date = (DateTime)e.Item.DataItem;
	Literal litDia = (Literal)e.Item.FindControl("litDia");
	HtmlTableCell tdDia = (HtmlTableCell)e.Item.FindControl("tdDia");
	int vencidos=0;
	int mantenimientos = 0;
	string usuarioid;
	string clienteid;
    if (Session["Usuarioid"] != null)
		usuarioid = Session["Usuarioid"].ToString();
	if (Session["clienteid"] != null)
		clienteid = Session["clienteid"].ToString();
	lstFechaMantenimiento.DataSource = _m.obtenerTodos("", "",usuarioid, "", clienteid);
	lstFechaMantenimiento.DataTextField = "sigrev";
	lstFechaMantenimiento.DataValueField = "id";
	lstFechaMantenimiento.DataBind();
	DateTime dt= new DateTime();
	DateTime dthoy = new DateTime();
	DateTime dtfecha = new DateTime();
	dt=DateTime.Now;
	string hoy = string.Format("{2}-{1}-{0}", dt.Year, dt.Month.ToString("D2"), dt.Day.ToString("D2"));
	dthoy = Convert.ToDateTime(hoy); 
	if (date.DayOfWeek == DayOfWeek.Saturday || date.DayOfWeek == DayOfWeek.Sunday)
		tdDia.Attributes.Add("class", "weekend");
		if (_actualMes == date.Month)
		{
			litDia.Text = string.Format("<a href=\"{0}?CalDate={3}-{2}-{1}\"{4}>{3}</a>", Request.Path, date.Year, date.Month.ToString("D2"), date.Day.ToString("D2"), (_specialDaySelected && date.Equals(_selectedDate)) ? " class=\"selected\"" : string.Empty);
			fechamantenimiento = string.Format("{2}-{1}-{0}", date.Year, date.Month.ToString("D2"), date.Day.ToString("D2"));
			dtfecha = Convert.ToDateTime(fechamantenimiento); 
			for (int i = 0; i < lstFechaMantenimiento.Items.Count; i++)
			{
				if (dthoy <= dtfecha)
				{
					if (fechamantenimiento == lstFechaMantenimiento.Items[i].Text)
					{	mantenimientos = mantenimientos + 1;	}
				}
				else
				{
					if (fechamantenimiento == lstFechaMantenimiento.Items[i].Text)
					{	vencidos = vencidos + 1;	}
				}
			}
			if (mantenimientos > 0)
				tdDia.Attributes.Add("class", "fechamantenimiento");
			if (vencidos > 0)
				tdDia.Attributes.Add("class", "vencido");
		}
		else
			litDia.Text = string.Format("<span>{0}</span>", date.Day.ToString("D2"));
		tdDia.ID = string.Empty;	
	}
}

请有人帮我。

提前。

Please, someone could help me.
thans in advance.

推荐答案

使用 System.Web.HttpContext.Current.Session 类来读取会话变量。

例如 var param = System.Web.HttpContext.Current.Session [loginParameters]。

Use the System.Web.HttpContext.Current.Session class to read session variables.
For e.g. var param = System.Web.HttpContext.Current.Session["loginParameters"].
