更新面板内的按钮导致错误 [英] Button inside update panel causing error

问题描述

所有人，\\ /


这是我的方案：

- 当用户点击按钮（更改部分按钮）时，它会导致出现另一个按钮（提交按钮）。我需要在updatepanel中放置提交按钮，否则当用户点击更改部分时不会显示按钮。

- 现在出现提交按钮，但是当我点击提交时，会出现此错误：



Microsoft JScript运行时错误：Sys.WebForms.PageRequestManagerParserErrorException：无法解析从服务器收到的消息。



我已尝试将change causevalid更改为false并添加

 <  触发器 < span class =code-keyword>>  
 <   asp：AsyncPostBackTrigger     ControlID   =  btnSubmit    EventName   = <跨度class =code-keyword>点击    /  >  
 <   / Triggers  >  

更新面板属性但不起作用。还有其他想法如何解决这个问题吗？

以下应该有所帮助： Sys.WebForms.PageRequestManagerParserErrorException - 它是什么以及如何避免它 [ ^ ]

Hye all,

Here is my scenario:
- When user click on a button (Change Section button), it causes another button (Submit button) to appear. I need to put the submit button inside updatepanel otherwise the button wud not be displayed when user click change section.
- Now the submit button appears, but when i click submit, this error occurs:

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed.

I have tried change causevalidation to false and add

<Triggers>
           <asp:AsyncPostBackTrigger ControlID="btnSubmit" EventName="Click" />
       </Triggers>

in update panel properties but neither works. Any other idea how to solve this?

<asp:UpdatePanel ID="UpdatePanel2" runat="server">
   <ContentTemplate>


                 <div id="divSubmit" runat = "server" visible ="false">
