它在aspx页面中工作,但不会在ascx控件中触发。这是ascx的代码。请让我知道我错过了什么。所有剩余的控件都会触发,但计时器不会在我的aspx页面中触发:
<asp:ScriptManager ID= "SM1" runat="server" EnablePartialRendering="true">
</asp:ScriptManager>
<asp:UpdatePanel id="updPnl" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="TRUE">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="timer1" EventName="Tick" />
</Triggers>
<ContentTemplate>
<asp:Timer ID="timer1" runat="server" Interval="1000" OnTick="timer1_tick"></asp:Timer>
<asp:Label ID="lblTimer" runat="server" Interval="1000" Enabled="False"></asp:Label>
protected void Page_Load(object sender, EventArgs e)
{
if (!SM1.IsInAsyncPostBack)
Session["timeout"] = DateTime.Now.AddMinutes(5).ToString();
if (!IsPostBack)
{
//ScriptManager.RegisterStartupScript(this, this.GetType(), "test", "javascript:f1();", true);
fillQuestionsLabel();
timer1.Enabled = true;
}
}
protected void timer1_tick(object sender, EventArgs e)
{
if (0 > DateTime.Compare(DateTime.Now,
DateTime.Parse(Session["timeout"].ToString())))
{
lblTimer.Text = "Number of Minutes Left: " +
((Int32)DateTime.Parse(Session["timeout"].
ToString()).Subtract(DateTime.Now).TotalMinutes).ToString();
}
}
答案 0 :(得分:0)
计时器引用Timer1但是当用户控件被渲染时,它将具有新分配的名称,因为它位于用户控件上。做一个查看源,你会看到这种情况。
<asp:AsyncPostBackTrigger ControlID="timer1" EventName="Tick" />
添加ClientIDMode =&#34;静态&#34;如下所示。这假设此控件仅在页面上被删除一次,否则您应该将Timer1的Timer1回发触发器设置为Timer1.ClientID()
<asp:Timer ID="timer1" ClientIDMode="Static" runat="server" Interval="1000" OnTick="timer1_tick"></asp:Timer>
