问题描述
我遇到一个有趣的问题。我们使用母版运行一个网站,并在页面中的一个,我需要建立一个更新面板完成后将显示SSID组。
I am experiencing an interesting issue. We are running a website using masterpage and in one of the pages, I need to create an update panel that will display group SSID on completion.
因此,在内容placesholders之一,我把这个在:
So, in one of the content placesholders, I put this in:
<asp:ScriptManager ID="scManagerConfirm" runat="server" />
<asp:Timer ID="tmrStatus" OnTick="tmrStatus_Tick" Enabled="false" runat="server" Interval="5000" />
<asp:UpdatePanel ID="upnlStatus" runat="server" UpdateMode="Conditional">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnConfirm" />
<asp:AsyncPostBackTrigger ControlID="tmrStatus" />
</Triggers>
<ContentTemplate>
<asp:Panel ID="pnlStatus" CssClass="appStoreStatus" Visible="false" runat="server">
<p><asp:Literal ID="litStatusText" runat="server" Text="<%$ Resources:GRes, StatusProcessing %>"></asp:Literal></p>
</asp:Panel>
</ContentTemplate>
</asp:UpdatePanel>
<asp:Button ID="btnConfirm" OnClick="btnConfirm_OnClick" Text="<%$ Resources:GRes, Confirm %>" CausesValidation="true" UseSubmitBehavior="false" runat="server" />
背景code是简单的:
background code is simple:
protected enum RequestStatus { Unprocessed, Processed }
protected void Page_Load( object sender, EventArgs e ) {
}
protected void btnConfirm_OnClick( object sender, EventArgs e ) {
pnlStatus.Visible = true;
tmrStatus.Enabled = true;
}
protected void tmrStatus_Tick( object sender, EventArgs e ) {
if (GetStatus() == RequestStatus.Processed) {
litStatusText.Text = "SSID: " + GetSSID();
tmrStatus.Enabled = false;
}
}
private String GetSSID() {
return "S-12345-1235-1235-1235";
}
private RequestStatus GetStatus() {
return RequestStatus.Processed;
}
现在,我遇到的问题是,这是行不通的。它的工作原理,如果我使用PostBackTriggers而不是异步的。然而,这不是我想要的功能。我试图把按钮和定时器到的UpdatePanel无济于事。
Now, the problem I am experiencing is that this doesn't work. It works if I use PostBackTriggers and not Async ones. However, that is not the functionality I would want. I have tried to put button and timer into UpdatePanel to no avail.
任何想法可能是错误的吗?
Any ideas what could be wrong with this?
推荐答案
此问题现在已经解决了。我所要做的就是增加异步=true将:
This problem is now solved. All I had to do was add Async="true" to:
<%@ Page Language="C#" MasterPageFile="~/FlipitAdminPortal.Master" AutoEventWireup="true" CodeBehind="AppUpload.aspx.cs" Inherits="FlipitAdminPortal.AppUpload" Async="true" %>
