How do I solve the error 'System.Web.UI.MasterPage' does not contain a definition for

c# asp.net master-pages

Ok, here is the thing, this works sometimes and then when I add another property or recompile it would give me an error. it turns out it is compiler issue. To get around the issue, I had to create a App_Code directory under the root and made a class. When I get the error telling me there is no DivWidth defined, I simple make a code change in the class I created and the site compiles in the proper order. It took opening a case with MS, who was not very helpful, for me to find this workaround. Hope this helps someone else who runs into this strange issue.

I have two master pages and a content page. On my local machine this code works, but once I uploaded to the server I got the following error:

Compilation Error Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: CS1061: 'System.Web.UI.MasterPage' does not contain a definition for 'DivWidth' and no extension method 'DivWidth' accepting a first argument of type 'System.Web.UI.MasterPage' could be found (are you missing a using directive or an assembly reference?)

Source Error:

Line 84:
Line 85:
Line 86: this.Master.Master.DivWidth = 955; Line 87: SimpleElementCollection restrictedIds = new SimpleElementCollection(); Line 88: restrictedIds.Add(new SimpleElement(priceModifierPriceTypeId));

Source File: c:\Inetpub\testsite\shop\Default.aspx.cs Line: 86

Base Masterpage cocde:

public partial class global : System.Web.UI.MasterPage
{
public int DivWidth { get; set; } 

    protected void Page_Load(object sender, EventArgs e)
    {
            SetBodyClass();
          if (DivWidth < 1)
        {
            DivWidth = 768;
        }
    }

Base Masterpage aspx:

Second Master Page:

<%@ Master Language="C#" MasterPageFile="~/global.master" AutoEventWireup="false" CodeFile="shopFalcon.master.cs" Inherits="shopFalcon" %>
<%@ Register TagPrefix="FALCON" TagName="FeatureProducts" Src="~/FalconShopRightHand.ascx" %>
<%@ Register TagPrefix="FALCON" TagName="ProductSearch" Src="~/FalconProductSearch.ascx" %>
<%@ Register TagPrefix="FALCON" TagName="AbuseText" Src="~/FalconAbuseLinkDisplay.ascx" %>

<asp:Content ID="Content1" ContentPlaceHolderID="headPlaceholder" Runat="Server">
</asp:Content>

nothing in the code behind cept empty code behind

My content page:

<%@ Page Language="C#" MasterPageFile="~/shop.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="shopFalcon_Default" Title="Shop Homepage" %>
<%@ MasterType VirtualPath="~/shop.master"%>


<asp:Content ID="Content7" ContentPlaceHolderID="leftColPlaceHolder" Runat="Server">
<asp:Image ID="Image1" runat="server" ImageAlign="Right" ImageUrl="~/images/Free+Shipping+01.jpg" CssClass="img"/>
<h1>Shop Anytime, anywhere. </h1>

<div id="shopByBrandDiv">
    </asp:Content>

My code behind:

  protected void Page_Load(object sender, EventArgs e)
        {


            this.Master.Master.DivWidth = 955;
    }

Again this works in Visual Studio using the built in web server but delpoying to the production server running IIS6 I get that error stated above.

Any ideas?

@Moo-Juice Well I would assume so, as this same code works on my local. I use it in Base Masterpage aspx and set it in that code behind and my content page

Sorry, but in your pasted-code I couldn't see anywhere that DivWidth actually did anything.
James Campbell over 13 years

@Moo-Juice Look again it is set in two places and called in this line in the base masterpage.aspx <div id="content" style="width:<%=DivWidth%>px;">
Moo-Juice over 13 years

Yes, I saw that. What I am saying is, the property declaration itself, given the code you have given, doesn't do anything. It's just get; set;. Are you missing something you haven't pasted?

@Moo-Juice In c# 3.0 MS introduced a new syntax for a property called an auto-implemented property, which allows you to create properties without get and set accessor implementations.

@James, Ah I see. I didn't know that. Thanks for the information.

hm, IMO this should NEVER work since you need a cast from MasterPage to your own class ((global)this.Master.Master).DivWidth = 955;
James Campbell over 13 years

It works both ways but I have the same issue no matter with or without the cast. I declear the master type so the class knows that this.master.master is global during runtime. It also knows this.master is shop.master. Soemtimes when I try the cast I get cannot convert type global to type masterpage. So I left it this.master.master .
