asp.net timer tick 事件不触发问题。用的是AJAX控件

[全栈极简]

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

scriptmanager放在最上面

代码如下： <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional"> <ContentTemplate> <asp:Timer ID="Timer1" runat="server" Interval="1000" OnTick="Timer1_Tick"> </asp:Timer> <asp:Label ID="txtTime" runat="server" Text="Label"> </asp:Label> </ContentTemplate> <Triggers> <asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" /> </Triggers> </asp:UpdatePanel>
