[英]asp.net timer not firing the updatepanel
我的aspx頁面內容頁面中有一個表（也使用母版頁）問題是Timer似乎沒有在進行異步回發，甚至沒有按以下方法嘗試在VS中嘗試新的解決方案代碼，並且每隔10秒刷新一次事件updatepanel即可正常工作。 因此，我相信代碼很好，但是有一些事情阻止了它的正常工作，我無法確定是什么。

背后的代碼
protected void TimerPrayer_Tick(object sender, EventArgs e)
{
ReadMyData();
}
也許可以使用trigger 。因為更新面板回發可以與trigger一起使用 。
您不必在更新面板中使用計時器，而在更新面板之外使用計時器。 並以在更新面板中使用計時器為例
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" />
</Triggers>
<ContentTemplate>
<!-- your content here, no timer -->
</ContentTemplate>
</asp:UpdatePanel>
<asp:Timer ID="Timer1" runat="server" Interval="5000" OnTick="Timer1_Tick">
</asp:Timer>
的源代碼
我在頁面加載中停止了回發
ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "setDOM", "$(\"#divDigitalClock\").clock({ \"langSet\":\"en\",\"format\":\"24\"});", true);
我有同樣的問題。 我在更新面板中放置了一個計時器。 它根本沒有觸發OnTick事件回調。 我將計時器移到了更新面板之外，然后它開始在回調中觸發。 然后，我在更新面板中為計時器添加了一個觸發器，它可以正常工作：
<asp:UpdatePanel ID="UpdatePanelChart" runat="server">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="tmChartPanel"
EventName="Tick" />
</Triggers>
