如何讓主頁面不閃爍？

我正在構建一個ASP.NET應用程序，並希望使用母版頁來顯示品牌和導航信息，並在幾個內容頁面中移動。但是，每次嘗試加載新內容時，整個頁面都會閃爍。無論如何要避免這種情況？如何讓主頁面不閃爍？

母版頁：

<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Site.master.cs" Inherits="Interface.Site" %> 
    <%@ Register TagPrefix="customControl" TagName="NavigationBar" Src="NavigationControl/NavigationControl.ascx" %> 
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 

    <html xmlns="http://www.w3.org/1999/xhtml" > 
    <head runat="server"> 
     <title>Registration</title> 
    <asp:ContentPlaceHolder ID="head" runat="server"> 
    </asp:ContentPlaceHolder> 
    <link href="Stylesheet.css" rel="stylesheet" type="text/css" /> 
</head> 
<body> 
    <form id="RegistrationMasterForm" runat="server"> 
    <div> 
    <asp:ScriptManager ID="ScriptManager" runat="server" EnablePartialRendering="true"> 
     </asp:ScriptManager> 

     <%-- Contents of this div span the top of the page for branding --%> 
     <div id="BrandingBanner"> 
      <asp:Image ID="Banner" runat="server" 
       ImageUrl="Images/BrandingBanner.png"/> 
     </div> 

     <%-- Navigation Bar, the contents of this div should remain unchanged --%> 
     <div id="NavigationBar"> 
      <customControl:NavigationBar ID="navBar" runat="server"/> 
     </div> 

     <%-- Contains any forms or controls that may be uniquie to the page --%> 
     <div id="FormControls"> 
      <div id="FormContent">    
       <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">   
       </asp:ContentPlaceHolder> 
      </div>    
     </div> 

    </div> 
    </form> 
</body> 
</html>

內容：

<%@ Page Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="WebForm2.aspx.cs" Inherits="Interface.WebForm2" Title="Untitled Page" %> 
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server"> 
</asp:Content> 
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server"> 

     <asp:UpdatePanel ID="UpdatePanel1" runat="server"> 
      <ContentTemplate> 
       Check me out! I am content for the master page! 
       <asp:Button ID="Button1" runat="server" Text="Next" onclick="Button1_Click" /> 
      </ContentTemplate> 
     </asp:UpdatePanel> 
</asp:Content>

內容背後的代碼：

public partial class WebForm2 : System.Web.UI.Page 
{ 
    protected void Page_Load(object sender, EventArgs e) 
    { 

    } 

    protected void Button1_Click(object sender, EventArgs e) 
    { 
     Response.Redirect("WebForm3.aspx"); 
    } 
}

因爲你正在做一個Response.Redirect而閃爍。我認爲有辦法動態地將控件加載到同一頁面，但我沒有嘗試過。 – Greg 2009-10-14 18:50:57

我現在確信我的重定向是壞的，但任何人都可以建議如何更改內容，同時避免閃爍？ – ProgrammingPope 2009-10-14 19:24:08
