问题描述
我有一个带有 asp:Timer 的 asp:UpdatePanel.这些位于主/内容页面中.代码如下:
I have an asp:UpdatePanel with an asp:Timer. These are in a Master/Content Page. The code is below:
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:Timer ID="Timer1" runat="server" Interval="5000" OnTick="Timer1_Tick"></asp:Timer>
</ContentTemplate>
</asp:UpdatePanel>
但是当计时器触发时,我收到以下错误:
But when the timer fires, I get the folowing error:
Microsoft JScript 运行时错误:Sys.WebForms.PageRequestManagerParserErrorException:无法解析从服务器收到的消息.此错误的常见原因是通过调用 Response.Write()、响应过滤器、HttpModules 或启用服务器跟踪来修改响应.详细信息:在 ' 附近解析错误
这适用于独立的 Web 表单,但不适用于带有母版页的内容页面.
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near '
This works in a standalone web form, but not in a content page with a master page.
谁能解释一下解决方法?
Can anyone explain a fix for this?
在此先感谢您的帮助!!
Thanks in advance for any help!!
推荐答案
UpdatePanel
中有 Timer
控件有什么具体原因吗?
Is there a specifc reason why you have the Timer
control in the UpdatePanel
?
每次我需要使用 Timer
控件来引起 UpdatePanel
刷新时,我都会像下面这样设置它并且它与 MasterPages 一起工作得很好代码>:
Every time I have needed to use a Timer
control to cause an UpdatePanel
refresh, I have set it up like the following and it works fine with MasterPages
:
<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>
使用 Trigger
使 UpdatePanel
从 Tick
事件刷新.如果可能,您只想在 UpdatePanel
中嵌入内容.
Use the Trigger
to cause the UpdatePanel
to refresh from the Tick
event. You only want to embed content in your UpdatePanel
if possible.
