计时器 Tick 事件未触发 [英] Timers Tick event not firing

问题描述

有一个简单的代码，我在其中添加了一个计时器并生成了滴答事件，但该事件没有触发.

There is a simple code in which I added a timer and generated tick event but the event is not firing.

<asp:Timer ID="Timer1" runat="server" Interval="1000" OnTick="Timer1_Tick" Enabled="True" EnableViewState="True" ViewStateMode="Inherit" ClientIDMode="Inherit"></asp:Timer>



protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        setImageurl();
        //Timer1.Tick += new EventHandler(Timer1_Tick);
        //Timer1.Interval = 1000;
    }
}
void setImageurl()
{
    Random _rand = new Random();
    int i = _rand.Next(1, 4);
    Image1.ImageUrl = "~/ImagesSlideshow/" + i.ToString() + ".jpg";
}
protected void Timer1_Tick(object sender, EventArgs e)
{
    setImageurl();
}

我不知道为什么会这样.帮帮我.

I dont know why this is happening. Help me out.

推荐答案

在 ScriptManager 上设置 EnableCdn="true" 就可以了，只是在我的侧面:

Set EnableCdn="true" on the ScriptManager and it will work, just tried it on my side:

<form id="form1" runat="server">
    <asp:ScriptManager ID="ScriptManager1" runat="server" EnableCdn="true"></asp:ScriptManager>
    <asp:Timer ID="Timer1" runat="server" OnTick="Timer1_Tick" Interval="1000"></asp:Timer>
    <asp:Image ID="Image1" runat="server" />
</form>
