UpdatePanel導致整頁回發

我有UpdatePanel的問題，其中它始終導致一個完整的頁面回發，而不是一個異步之一。UpdatePanel導致整頁回發

這裏的ASPX代碼

<%@ Page language="c#" Codebehind="RegistrationsOld.aspx.cs" AutoEventWireup="True" Inherits="Registrations.Register" %> 
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" > 
<html xmlns="http://www.w3.org/1999/xhtml"> 
    <head> 
     <title>Registrations</title> 
    </head> 
    <body> 
     <form id="_mainForm" runat="server"> 
      <asp:ScriptManager ID="_scriptManager" runat="server"></asp:ScriptManager> 
      <asp:UpdatePanel ID="_updatePanel" runat="server"> 
       <ContentTemplate> 
        <asp:Button ID="_postBack" runat="server" Text="Postback!!!" /> 
        <%=DateTime.Now%> 
       </ContentTemplate> 
      </asp:UpdatePanel> 
     </form> 
    </body> 
</html>

背後的邏輯

在生成的HTML我注意到，所有登記的UpdatePanel缺少JavaScript邏輯，什麼都可以沒有錯誤的代碼？

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" > 
<html xmlns="http://www.w3.org/1999/xhtml">

什麼用的ID屬性下劃線的？ – 2009-08-06 20:31:44

我發現問題是問題!!!

所以，心理注：不允許使用xhtmlComformance的：d

更多信息，可以發現here。

摘錄：

除非你知道你的網站在XHTML模式下運行時（和你沒有時間尚未確定）的已知問題，我總是建議取下部分從您的web.config文件（或者您可以明確地將其設置爲「Transitional」或「Strict」）。

這將使您的HTML輸出標準兼容。除此之外，這將導致您的服務器控件的HTML格式良好 - 意味着打開和關閉標籤元素始終匹配。當您使用AJAX技術動態替換頁面上某些HTML元素的內容（否則客戶端JavaScript有時會對容器元素感到困惑並可能導致錯誤）時，這一點尤其重要。它也將確保ASP.NET AJAX在您的網站上正常工作。

我不認爲這是一個問題。我們在所有頁面中使用帶有DHTML一致性的UpdatePanel。那麼你是說刪除一致性自動使更新面板只發送部分頁面回發？ – 2009-08-06 20:34:42

XhtmlCompact to Legacy was the problem http://weblogs.asp.net/scottgu/archive/2006/12/10/gotcha-don-t-use-xhtmlconformance-mode-legacy-with-asp-net-ajax .aspx – Paleta 2009-08-07 12:43:21

-2

我的第一個想法是從所有的ID名稱中刪除下劃線。

您可能需要添加「的EnablePartialRendering = true」添加到腳本管理

雖然這是默認值，但值得嘗試。 – 2009-08-06 20:36:45
