Web Forms :: The Page Contains Markup That Is Not Valid When Attached To A Master Page
Feb 9, 2010
I have a web application with a Master Page, two pages in my project needed to be out of the master page template and display different styles so I indicated the folder that contains the style sheets for each one of my pages like this:
<%@ Page Language="vb" AutoEventWireup="false"MasterPageFile="~/Site1.Master" CodeBehind="Welcome.aspx.vb"
Inherits="B0_1.Welcome" StylesheetTheme="Default" %>
(or StylesheetTheme="Print" accordingly) [code]...
App_Themes directory contained only Default
The application runs ok but every time I want to modified something the first time I open the page in the design view shows me the following error:The page contains markup that is not valid when attached to a Master Page correct the problem in the code view
Then I click view code and it is highlighted the wrong section that is always all what is in the ContentPlaceHolderID="head".If I cut this bit, go to the design mode and then go back to the code mode and paste the bit of code again I can see the design mode without problems and switch to the code view as well without problems. It is very anoying and I don't know if it will affect
me in other ways.

In my ASP.Net web application, I have a base page that implements functionality that spans all pages of the web application and my web pages derive from this base page. Since there is a single master page for the entire website, I don't want to attach the master page in each of the web pages. So I attached the Master page via the basepage's OnPreInit method as follows:
protected override void OnPreInit(EventArgs e)
{
this.MasterPageFile = "~/Site.master";
base.OnPreInit(e);
}
However, when I switch to Designer view, I get the "Master Page Error"; The page has controls that require a Master Page reference, but noe is specified. Correct the problem in Code View.When I run the application, the webpage shows up correctly.What should be done so that the designer shows up correctly without having to go and set the master page explicitly in each of the web pages?
BTW, I am on Visual Studio 2010 and .Net 4.0

I am working on masterPage/sub masterpages, all worked fine until this morning.When I open a .aspx which uses masterpages, in the design view it shows the error message..
I've checked both master pages several times, all tags are matched and visual stuido itself doesn't indicate any errors. Also in debug mode the html page is generated without any problems..

I have added a favicon to my site but it will not appear. I have the following two lines in the master page markup:
[Code]....
When the first page that uses the master page is rendered in the browser, these links are:
[Code]....
This is as I would expect yet the favicon does not appear. It appears fine on any basic html pages but simply won't on any pages that are based on the master page.

My Project is a normal web site, not a Web Project, and I am using VS 2005.
I am trying to define common Master Page Type in app_code which has an area to display error messages and the like. Very simple.
I added the following in app_code:
[Code]....
Also, I added the following in Master Page Source Declaration:
[Code]....
Also, I added the controls tblrowErrMsg and lblErrMsg as server controls to the Master Page.
Why I am doing this ?
This will allow me to display error messages from nearly any where inside the code in code-behined, app_code, and other core Class Projects (DLL).

I am wondering if there is anyway to grab the html that is generated from an ASP page.I am trying to pull a table from the page,and I foolishly used a static html page so I would not have to be constantly querying the server where this page resides while I tested out my code.The javascript code I wrote to grab to unlabeled table from the page works.Then when I put it into practice with the real page and found that the ASP page does not generate a viewable page with a jquery .get request on the URL.
Is there any way to query the page for the table I need so that the ASP page returns a valid page on request?(I am also limited to using javascript and perl for this,the server where this will reside will not run php and I have no desire to learn ASP.NET to solve this by adding to the issue of proprietary software)

Having a very strange problem and just wondered if anyone could shed some light on it. I have a page that takes a file and posts it (using a flash control) to another page on the same site. Now this other paged is used simply to take the file from the request and save it to disk. However when i try and set a session value there the calling page can not access this session variable (no matter how long i do a thread.sleep. It is simply nit finding the variable.
When i looked deeper into this I ran trace.axd and much to my surprise the page that is called does not show up in the list. But it is defnitely being called as the file that the original page sent has been saved to disk.

I have a master page setup that is used throughout my site that is basically a header with a menu. I recently added a textbox and a button to this master page which is to be a quick search box that is available anywhere in the site. When a user enters text into the search box and hits the button, I need to load the actual content page which is used to search and show search results (which also uses this same master page), and have the text entered available so the search can be triggered automatically. Again, this search text box and button is now in my master page so it could be triggered from anywhere in the app... it serves as a convenient way to do a basic search from anywhere in my app, without having to first navigate to the actual 'search page' that already exists. You can also navigate to the actual search page, which uses the same master page, where there is many more search options.I'm thrown off by the master page arrangement, which I have not used until this project. What do I do?

I have a master page containing a tree and 3 dropdown lists. I am populating a context menu on right click of each node, and when clicked on any item of the context menu, it navigates to required pages.
My problem is after navigating to the required page, the selected values from the drop down lists and the selected node from the tree are getting cleared.
I can set the selected values for the dropdown lists by making some properties in master page.
But how do i maintain the selected node?
In my content page, i have got the valuepath of the right clicked node.
Or is there any other way than setting the properties in master page?

I'm trying to dynamically change the look of my main master page depending on what nested master page that the current content page is using .
So for example.
Main master page = main.master
My nested page = nested.master (uses main.master)
content page = content.aspx (uses nested.master)
So in the Page_Load event of main.master I want to add a switch statement that will check to see what nested master page is currently being used by content.aspx, or whatever content page is loaded.
So far I have got
protected void Page_Load(object sender, EventArgs e)
{
string nMaster = //This is the line of code that I am looking for.
switch(master)
{
case "nested.master":
//all my logic here.
break;
}
}

I have a nested master page that has its own master page. The parent master page has a property defined in its code behind.
Public ReadOnly Property SelectedPage() As String
Get
Return _selectedPage
End Get
End Property
How can I reference the parent master page's property from within either the child master page's code behind Page_Load or aspx template page?

My master page looks like:
<head runat="server">
<title>
<asp:ContentPlaceHolder ID="PageTitlePlaceHolder" runat="server" />
</title>
Content pages look like:
<asp:Content ID="TitleContent1"
ContentPlaceHolderID="PageTitlePlaceHolder" runat="Server">
My Page
</asp:Content>
This works by placing the content page specific title on the page ("My Page" in this example). Now I want to add a global prefix to the title in my master page for the site name. So I want:
<head runat="server">
<title>
Example.com:
<asp:ContentPlaceHolder ID="PageTitlePlaceHolder" runat="server" />
</title>
However, when I do this content pages are still rendered without "Example.com" in the tile, it's like it's ignored.
Why is this happening and how can I achieve this?

I want to share a common page load and page init events sequence between Master page and child page and User Control as described below:
Let us have the following components:-
1. TestMaster.master -> It is the master page
2. TestChild.aspx -> It is the Child page
3. TestUserContrl.ascx -> It is the UserControl present within the TestMaster.master page.

Per different user mode, some pages should not be accessible by users unless they have a valid session key.In your opinions -- would it be better to have a list of acceptable pages in the master page, and check if the current page is valid for the current user? Or handle this on every child page?I'm thinking master page, just want to hear what your input would be.

I'm using Vs2010 professional. I was working with a large WebSite (folder) project at work using IIS7 and tried to attach the debugger to the w3wp.exe for debugging an aspx page in IE8 after setting breakpoints in the javascript for the page and in the Page_Load in the code behind. I got a "first chance exception of type 'System.InvalidOperationException' occurred in System.dll" in my debug output, so I gave up for the moment. I created a default website project in the root of IIs7, and set it up as an application in IIs7 with the default app pool.
I tried entering a little javascript in the head, and set a breakpoint, and set a breakpoint again in the Page_Load. I attached the debugger again to w3wp.exe. I see the assemblies load in the debug output and nothing happens:

I have a 3 level nested master pages and a content page. parent1 is the top parent, parent2 is parent of parent3 and parent3 is the parent of the content page.
I get an error 'Cannot find ContentPlaceHolder xxx...' where xxx is a ContentPlaceholder. It resides in parent2 and content page is trying to fill it.
Can content pages only use their direct parent ContentPlaceHolders or can they also use any of the higher master pages?
