I am building an ASP.NET application and would like to use a master page

  • 0

I am building an ASP.NET application and would like to use a master page to display branding and navigation info and move through several content pages. However, every time I try to load new content the entire page flickers. Is there anyway to avoid this?

Master page: 

    <%@ 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>

Content:

<%@ 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>

content code behind:

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");
    }
}

    The control event triggers a post back to your page, which typically creates the “blanking” effect that you see. To mitigate this, you may want to consider using some sort of Ajax solution to cause a partial postback or async postback to prevent the “blanking”.

    However in the particular case of your button click, if all you are trying to do is bring the use to another page, you really should just use an <a href="WebForm3.aspx"> tag and avoid using Response.Redirect.
