looking for information on how to do this. our company has one website, with several different applications. the way we have set it up is that we have been creating these different applications as websites, we have one Master page for the whole site, so when we create a new website we also create a virtual site with our master page in it. We are using VS 2008 now and what we want to do is make the change to creating web applications but I have not been able to figure out how to bring our master pages into the application, without bringing the actual pages into the app. the only thing I have been finding is people creating the master page file in the web application, that will not work for us, as we have to many applications and if there is a change in the master page it has to show on our whole website, so we need to either be able to bring our master page in as another project or set it up as a virtual directory, or reference it in the web.cofig somehow, but the master page needs to stay in it's own directory and only referenced.
For those who setup muli project areas in ASP.NET MVC 2 in VS 2010, I have a few questions for you:
Can other project areas use one master page? Or does each have to have their own master page? What about the web.config file? Does each area need the config file? Or does it rely on the master? I tried removing the master page reference, but I get an intellisense error and failed to monitor changes after following this: [URL]
I assume I need to leave in the master page so that at least works.
I am showing Custom Error in my page.if somehting happend wrong. but if the same error occured in my subview master page I am not able to show the Custom error page on Entire page its showing me that Error page under subview master page.I am attching the Screen shot.Can any body help me out how to show the Error page on entire page if something happend in any where submaster or other page.Here is the code that I am using in web config file to show custom Error page..

Here I know the issue what's going on.This issue is occurring because i am using AJAX to partially load the contents of the tabs after the initial page load so the error is occurring AFTER my master page has been loaded.What I need to do is provide a javascript function to handle the error after the ajax call has returned and redirect to the error page.How to write this Javascript and where Do I need to write this?
We have two projects. One is in MVC and the other is the traditional Asp.Net project. We are trying to share a common Master Page for both the projects. The Master page for the MVC project is already using a form tag with runat="server" attribute because it's using a traditional ASP.Net control for the navigation menu. The ContentPlaceHolder is outside this form.
UPDATE: Found the answer here: [URL] <form id="Form1" runat="server"> ....... <asp:ContentPlaceHolder ID="MainContent" runat="server" /> </form>
I am trying to add a .aspx page in the project , but while adding the .aspx page i am not getting the option to choose existing master pages. I remember long back i used to get that option to select the master page.
In an ASP.NET web app written in VB.NET, I need to load and store a large read-only hash table that is frequently accessed by the application. It only needs to be loaded once on application start, is never updated and can be accessed by any session at any time.
If I load the hash table into a private member in a (global) module, a lookup to it takes one 20th of the time compared to storing the hash table in the Application or Cache object. Is there any reason why I should not do this, or should Application or Cache always be used to store in-memory objects in an ASP.NET web application?
I have two member roles at my project: 1.) Administrator 2.) Member
From the toolbox in Visual Studio 2008, I have dragged and dropped the create user wizard into the stage. I aim that a guest can register itself and automatically join the "member" role. Not the role "administrator". How can I do that?
I have a MasterPage project which is a class library project (it includes themes, style sheets, menus etc) and all applications use them.
I am using the BasePage concept for dynamically adding title,meta tags and descriptions. This BasePage Class inherits system.UI.Page and the aspx pages in the project inherits the BasePage class.
Now i need to move this BasePage class from my application to the Master Page Project so that all the projects/applications can reuse the same code.
I tried add the basepage.cs in the App_code folder and tried calling it in the page directive like below
<%@ Page Language="C#" MasterPageFile="~/Master/Layout/MasterPage.master" AutoEventWireup="true" CodeBehind="xxxx.aspx.cs" CodeFile="xxxx.aspx.cs" Inherits="xxxx" ValidateRequest="false" EnableEventValidation="false" ViewStateEncryptionMode="Never" CodeFileBaseClass="~/Master/App_Code/BasePage<Page>" Title="Title" Meta_Keywords="xxxx,yyyy,zzzz" Meta_Description="This is a test" %>
But i am getting error
Could not load type '~/Master/App_Code/BasePage<Page>'.
This was working fine till the BasePage class was inside the application. But once i moved it out of the project and added it to the master page project i getting this error.
I get the following error in my imports statemnt Namespace or type specified in the Imports doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the alias name doesn't contain other aliases. I did add the required dll's in the References tab in Project Designer in Visual Studio also added it in imported namspaces, but i still get the error what should i do?
I have created the asp.net application, it was working fine in the Dev environment. When i move the same application into production, it throws "BC30456: 'InitializeCulture' is not a member of 'ASP.fileretention_aspx'." error while loading the Default.aspx page. Initially this page was wotking fine, in the button click event this page is reloading, error accours while reloading the page.
In my app i have a master page that all content pages use. I would like to have a centralized area inside my master page that would handle displaying of error messages. So on my master page I would have the following this is where the content goes So when I would submit a content page, placeholder named "ErrorPlaceHolder" would be found and error would be displayed in the pages "Pre Render" event..I guess. How would I do that?
Description: An error occurred during the compilation of a resource required to service this request. review the following specific error details and modify your source code appropriately.
Compiler Error Message: BC30456: 'Eval' is not a member of 'ASP.InsertLTAS_aspx'.

Seems to be having problems with my databind control that i have set in my gridview with edit and delete options?
When Iuse FTB in a normal web form I am having no issues. However when I create a master page then a web form that uses that master page I get the following error when pulling text from the FTB control
A potentially dangerous Request.Form value was detected from the client (ctl00_ContentPlaceHolder1_FreeTextBox1="<b>My TEXT</b>")
I get this error only when it uses html tags and only when its in a form that uses a master page.

I am binding SQL data to a GridView. The GridView's DataKeyNames property is set to the SQL column called "utID"
I know that within the SQL results, some of the utID values are NULL. After databinding to the GridView, I need to enumerate through the GridViewRows an read the DataKey values. However, when I try this I get the following error:
No default member found for type 'DBNull'. I am using the code below.
What object types are stored within DataKeys (I thought it was just integers or strings)
How to handle a NULL datakey value to prevent this error occurring?
