Web Forms :: Trying To Use A MasterType TypeName To Access A Class With Master Pages? forums.asp.net

I'm trying to use a MasterType TypeName to access a class with master pages. This works when I'm using .NET 2.0, VS 2005, and C#. When I try this using .NET 3.5, VS 2008 and C# I get the error: The type or namespace name 'classA' could not be found (are you missing a using directive or an assembly reference?) and it is pointing to the Default.aspx.designer.cs In the default.aspx I have: <%@ Page Language="C#" MasterPageFile="... <%@ MasterType TypeName="classA" %> I have added a folder App_Code to my project and in that folder I have a class file "classA.cs" that contains: Using ... Namespace Project.App_Code { public class classA : System.Web.UI.MasterPage ... The main difference that I see from where it works and where it doesn't work is that where it doesn't work it uses the namespace called Project.So I figure my problem is in the including the class classA in the namespace or properly including the namespace and / or App_Code directory in the MasterType TypeName which I don't seem to be able to figure out.

Curious Problem With String www.vbforums.com

However when I run the project it says there is a build error and that the namespace could not be found or doesn't exist. I have added a namespace to the <pages><namespaces> part of the config file and that didn't fix it.

When I compile I get obviously get a The type or namespace name 'UserControlB' does not exist in the namespace 'MyProjectWeb.Common' (are you missing an assembly reference?) Why is that I can reference UserControlA but not UserControlB which are in the same namespace from the WorkFlowManager cs file? If I access the MyProjectWeb.Common namespace anywhere inside the MyProjectWeb, I can see both the user controls. Anywhere to look for errors?

Differences About Importing Namespace In C# And VB? stackoverflow.com

In VB, when we adding a new references - in my case web references -, it simply type namespace followed by the class name to make a new object.For example: Dim obj As NamespaceName.ClassName = New NamespaceName.ClassName Then I apply this concept in C#. So my code will be: NamespaceName.ClassName obj = new NamespaceName.ClassName ...and it doesn't work.Actually, is there any difference about Importing Namespace between those two?And also can you give me a little explanation about Project-Wide Default Namespace Imports in VB? UPDATE:My point is why "In C#, When I've typed NamespaceName, the ClassName was not listed in the Intellisense?".However, it did well in VB, do I have to import something?Maybe, there is something to do with the term "Project-Wide Default Namespace Imports". (CMIIW)

Avoiding Namespace Declaration In Each File? social.msdn.microsoft.com

One feature of C# compiler is that namespace declaration by default follows the folder name structure in the project. By e.g. you have MyProject1MyDrawing and inside you create a class MyPoint the namespace for MyPoint will be MyProject1.MyDrawing In VB I cant see any namespace declaration(apparently it implicitly 'inherits' the project(MyProject1) namespace). If I create a MyPoint and MyLine clases in the MyDrawing folder I need to surround each of created classes with "Namespace MyProject1.MyDrawing"..."End Namespace". Is it possible to automatically name the namespaces like in C# by the folder name?

Visual Studio :: How To Create A Folder In App_code Called "BL" forums.asp.net

I have a VS 2005 website project. I have created a folder in App_code called "BL". In BL folder, I have a User.cs class. So the structure is, App_Code/BL/User.cs. Now, I create a new aspx page. In this page, it is not detecting User.cs.. It is showing up .net framework's User(Page.User) class. I thought this might be a conflict of namespaces or something and so I gave a namespace to my User.cs. The namespace given for this class is Sitename.BL.. But the namespace(Sitename.BL) doesn't even show up in when I type "Using.. " If I create another cs in the BL folder, its able to recognize the class. I don;t know where I am going wrong. I don't want to create web application and create a separate BL class library and all for a small website as mine.

Visual Studio :: UpdatePanel Reference In Control.ascx.designer.cs Keeps Changing forums.asp.net

I have an annoying problem when I'm developing in Visual Studio 2010. I am using an UpdatePanel in my .ascx file like this: <asp:updatepanel id="upStuff" runat="server">....</asp:updatepanel> in my control.ascx.designer.cs, the update panel is being defined like this: protected global::System.Web.UI.WebControls.WebParts.updatepanel upSettings; this produces the error: "The type or namespace name 'updatepanel' does not exist in the namespace 'System.Web.UI.WebControls.WebParts' (are you missing an assembly reference?)" The actual namespace should be System.Web.UI.UpdatePanel. When I go directly into the designer.cs file and change it, it works. However, every time I go back into editing control.ascx and save, Visual Studio always changes it back to system.Web.UI.WebControls.Webparts.updatepanel. I'm not sure what is causing this. Is it how I should be referencing namespaces and classes in my project? I'm using .NET 3.5.

Visual Studio :: Folder Names Not Showing In Namespace Intellisense? forums.asp.net

When using VS2008 and C# I choose File - New - Web Site.I use namespaces in the aspx files in the same folder.The problem is that the aspx files in one folder can not access the aspx files in other folders even though the files in each of the other folders use the same namespace followed by the folder name. In fact, if I am in one folder and type the namespaces followed by a period, the other folder names are not displayed in intellisense, only the name of the folder name of the aspx file in which it resides is displayed on the intellisense. How can I get the other folder names to show in intellisense from any other folder that I am working in when coding in the code behind? fyi, in the html inherit I point to the namespace, the folder name and the code behind file then in the code behind file I code the namespace, the folder name the aspx file is in and the class is the name of the code behind file.

How To Fix Type Names Conflicts In Dynamic Data stackoverflow.com

We're working in a Dynamic Data project that will handle entities coming from two different namespaces: myModel.Abby and myModel.Ben. whose classes are: [code]... So myModel.Abby.Car and myModel.Ben.Car are homonym. when I try to register both ObjectContext's, an exception is thrown telling us that there are type name conflicts between the mentioned classes (although the types belong to different namespaces). How can we overcome type-name conflicts, caused by repeated type names among different namespaces?

WCF / ASMX :: Namespace Options In Generated Code forums.asp.net

I have a Solution in which I have A WCF Service web site project which then hosts two separate WCF Service Libraries (each in their own project). One of the Web Services is a Client to the other. When I click the ClientService and select Add Service Reference, it all adds properly, but when I go to build it, I get this error in the reference.cs (the generated file).The type name 'HostWCFService' does not exist in the type 'ClientService.ClientService' C:Users...Reference.cs I don't want it to create a ClientService.HostWCFService namespace, I want to be able to use the HostWCFService as its own namespace. I believe I've had this setup working before at one point; that is, I had this arrangement working before, but am not sure now if the host service was in a sub namespace of the project.
