Is there any way to access code behind for controls in content pages??
Actually i've a content page and i've added some controls(say button) to it. Now, if i want to write some code on button_click , how do i do it? because i'm not able to get to the code behind for these controls. I can only see Page_Load in the code behind aspx.cs page
I have a usercontrol on the content page. I'm trying to access this usercontrol's hiddenfield.
I was able to access it before applying the master Page. But once I changed the page to a content page , the value in the hiddenfield is showing empty.
alert(document.getElementById('<%=hidLat.clientID%>').value) is showing the value.
I have a property PickupHidLat defined on the ascx page and I'm using this property to access hidLat value on the content page.
objBLL.Latitude= DirectCast(uc_MyClient.PickupHidLat, HiddenField).value
why is the value null on the content page?
I have a Master Page which controls the styling of my site. In the Code Behind, there are a few class instances instantiated as well as variables. These classes validate user access and then create user objects
I have a few Web Content Forms which carries out instructions based on the user objects. So far it seems that on each Web Content Form I have to create new instances of the classes found on the Master Page. This is doubling my work for every Web Content Form.
Is there anyway I can inhereit Classes and objects instantiated in the Master Page Code Behind?
My project has the following repeater menu shown on the Master Page. I need this menu to remain hidden until the user logs in. How do I access from content page?

Today I got a strange problem,that is I am unable to access master page controls in its code behind,I am wonder because,I can able to access master page controls in their code behind of other projects/applications's master pages.
I know we can acess like this Label lblText = (Label)this.FindControl("lbluserName"); in that situation but I need to access div controls which are set to run at server.

On masterPage i have button btnTest, how hide button from masterPage on userControl.ascx

}
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'

I am an experienced web developer but sometimes ASP.Net is tricking me. I have a master page in asp.net. Then I have a page based on that master page (home.aspx). Now in home.aspx.cs I want to access the asp:content controls to add controls programmatically.
Aspx looks like this:
<asp:Content ID="leftCol" ContentPlaceHolderID="cphLeftCol" Runat="Server">
<asp:PlaceHolder ID="phLeftCol" runat="server">
</asp:PlaceHolder>
</asp:Content>
I would expect that I can reference "leftCol" from my code behind. But it's unknown there. For testing I added my own placeholder "phLeftCol". I can reference that without issues.
to whom it may concern,
I wish to access a public property in a master page from a nested content page
is there anyway to do that without using "master type"
i found this link
http://www.velocityreviews.com/forums/t110057-accessing-properties-from-nested-master-pages.html
but i dont understand what "companywide" is
((CompanyWide)this.Master.Page.Master).HtmlTitle = "now it is working";
i dont want to use "MasterType" i would rather cast..
I have a user control in the master of my website and I want change some property of that control from the content page.

In master page I am using asp content place holder. And in my child page I am using pure html coding. When I attach master page in my child page I am getting this error.Content controls have to be top-level controls in a content page or a nested master page that references a master page.
View 1 RepliesHere's the scenario: A class based on System.Web.UI.Page has been created. A number of content pages derive from this class. All of these content pages use the same master page. The content pages define controls which need to access things on the master page (in code-behind). This is fine - no problem. In particular, each content page has its own data grid. The grid on each page has the same name, so that common code can reference it. In fact, some event handling for the grids on each content page is identical, so would like to factor that code to the base class. Interestingly, I can actually define the event handler entirely in the base class, with no stub in the content class at all, because the wire-up of event handlers uses the event-handler name defined in the grid, and that name happens to be found in the inherited base class. All good and dandy... very cool in fact. The problem comes when the code in the base class needs to access any of the common elements from the content page's master. Remember, the master is the same, and I know the type of the master. I would like to do something like this in the base-class code:
((myMasterType)this.Master).PropertyofMaster=xxx;
The problem is, that myMasterType - the type of the master page the content pages are using - is not available at compile time, at least not from a class definition for a base page. I've found articles that claim that the class name of the master is available - and it is, but not from a separate class. I CAN see it and compile with the master's class name from, for example, the code behind of the various content pages. But the actually class simply isn't available, it seems, from a pure class (the base page class). Judging from other times this question has been asked, here are common misunderstandings offered as solutions: 1. Use a page directive to declare the master type. This is not even vaguely a part of the problem, as the issue is not code in the content page, but in a separate base class which content pages inherit from. That base class is a pure class -- no .ASPX file at all. 2. Pass a reference to the master object from the content page to the base class. This can be done, but is pointless, because I can already get it, using "this.Master" from the base class! But because the type of the master is not available at compile time from the base class, it can't be passed from the content page either - unless it is passed with type MasterPage, thus losing all the properties/methods publically defined in the specific master page class. 3. Move the base page class out of the App_Code folder because the app_code folder is compiled before the other classes, and thus before the master page class. Doesn't work -- put the master page class file right in the same folder with these content pages and their master page, and the master page class is still not available at compile time from within the class. Re-summarized: Base page inherited by content pages. Content pages all use a common master page. Want to access the public properties of that master page from the base page, at runtime. Barrier is that I can find no way from within the base class to cast the master page object to the actual master page subclass being used.
