Content Controls Allowed Only In Content Page That References A Master Page

Mar 10, 2016

Can I ask what this error refers to, (I have had it twice now over the last couple of days and then it goes away):

System.Web.HttpException: Content controls are allowed only in content page that references a master page.

This is followed by Stack Trace:

[HttpException (0x80004005): Content controls are allowed only in content page that references a master page.]
System.Web.UI.MasterPage.CreateMaster(TemplateControl owner, HttpContext context, VirtualPath masterPageFile, IDictionary contentTemplateCollection) +9744256

System.Web.UI.Page.PerformPreInit() +51
System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1104

I am not using any Content Place Holder or Master Page (does the error refer to the Site.Master file because while I can see it in. Solution Explorer, I never use it. All of my aspx files look like this along the top with no reference to Site.Master:

Code:

Access &lt;body Element From Content Page Via A Nested Master Page

May 19, 2010

All I want to do is access the <body> element from the code-behind of a content page and add a class name to it.

I have a top-level master page with the <body> element in it. Then I have a nested master page which is the master page for the content page. From the code behind of the content page I want to add a class name to the body element. That's all.

I have this in the top-level master:

<body id="bodyNode" runat="server">

I added this to the code-behind for the content page:

Master.bodyNode.Attributes.add("class", "home-page");

And I get a message that:

System.Web.UI.MasterPage' does not contain a definition for 'bodyNode

If I add this to the aspx content page:

<% @ MasterType VirtualPath="~/MasterPage.master"%>

The message then changes to:

bodyNode is inaccessible due to its protection level

I've wasted like 2 hours on what feels like something that should be really simple to do

Web Forms :: Interaction From Nested Master Pages To Content Page

Apr 12, 2010

I have 2 nested master pages, lets call them MP1 and MP2. MP1 is top level, MP2 is level

2. Then I have several content pages. Lets say I have 2 content pages for now CP1 and CP2. Each content page has a form that will have some user input and a SaveData()function that saves the data to a database. Each content page also has a "Save" button that calls the SaveData() function.

MP1 and MP2 have several link buttons. The functionality I need is this: Any time a user clicks on a link button in MP1 or MP2, the SaveData() function of the currently loaded page should be called. This is to save the data even if the user forgets to click the "Save" button before leaving the page.

So far I can do this from the link buttons in MP2. I followed the master pages tutorial # 7

In the .cs file for MP2, I declare:

public event EventHandler SaveData;

then i raise a "SaveData" event any time a link button in MP2 is clicked.in every content page (CP1, CP2 etc.) aspx file, I have Master Type directive to assign the Master Page to MP2.

in CP1, CP2 etc .cs file, i have the following code:
protected void Page_PreInit(object sender, EventArgs e)
{
//wire up the SaveData event from MP2 to Master_SaveData function in this page.
Master.SaveData += new EventHandler(Master_SaveData);
}
private void Master_SaveData(object sender, EventArgs e)
{
//when the MP2 SaveData event is raised, save the data in this page.
SaveData();
}

All of this works fine.Problem is I am not able to do a similar thing from MP1.What I have tried so far is to raise an event in MP1 that is handled in MP2. When the event is handled in MP2, it raises the SaveData event to be handled in the page. The event in MP1 is null and hence never raised.

Forms Data Controls :: Accessing Master Page Controls From Content Page Formview?

Sep 22, 2010

I have a master page with a textbox that I want to use for a search, and display the results on the content page.

I've dragged in the datasource to the content page, and configured the formview to use that datasource... almost.

The issue I'm having is that on the last step of the configure datasource wizard where you select the parameters, I want to select the master page textbox control for the search parameter... but of course it's not available in the list. The list only allows me to choose controls from the content page.

How do I set this master page search box as the parameter for my datasource?

Allowing The Content Page To Access The Master Page Controls?

Sep 13, 2010

I'm trying to make my masterpage work with my content page, allowing the content page to access the master page controls. I get the error:

Parser Error Message: The 'mastertype' directive must have exactly one attribute: TypeName or VirtualPath

This is on the lines:<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="viewProduct.aspx.cs" Inherits="AlphaPackSite.viewProduct"
MasterPageFile="MasterPages/Main.master"
title="Hi there!" [code]...

I'm a bit confused with namespaces and such so may have got them wrong, but all pages are in the same namespace now I beleive.

Update,When I turn it to:

<%@ MasterType VirtualPath="MasterPages/Main.master" %>

I keep getting the error: Compiler Error Message: CS0030: Cannot convert type 'AlphaPackSite.Main' to 'ASP.masterpages_main_master'

Source Error:

Line 147: public new ASP.masterpages_main_master Master {
Line 148: get {
