Feb 16, 2010

I used to be able to view the pages of my ASP.NET 3.5 website locally via the 'View in Browser' facility. However, this no longer works (for any page). All I get is a 'HTTP 404 Not Found' error message.

Where might I have screwed things up?

Web Page Visible In Xml Format In View Page Source But Looks User Friendly On Browser?

Dec 6, 2010

look at this sample link address: ( [URL] if you view page source in browser, you can see that it shows data in XML format (usng xsl.?). I need to implement a simple web page like that. I think that web site uses XML XSL I'm going to implement a web application in which will use data stored in sql database (or xml database or web service) and show these information like other normal web sites but in xml format in nice UI (using xsl?).That Weather website is only a sample to show what i want to do (i will not use any data from that site, my application is different).My requirement is being able to view page source only in XML format.Now I'm clear that xsl is the solution for that, but considering to use this method in xml/xsl in dynamic pages) My Question? It is important for me to make the web page output in xml format(visible in xml format in page view source) but looks user friendly for users. can i do it in ?

State Management ::show Cutom Page When Webpage Has Expired Error When Click Browser Back In 1.1?

Jul 26, 2010

I am using the following code to ensure that the web pages in my website are not cached by the browser:

this.Response.Expires = 0;

this.Response.AppendHeader("Pragma", "no-cache");


This is working fine & the browser displays a page with the message, "Warning. This page has expired....". Is there any way I can display a custom page instead of the default page shown by the browser?

VS 2010 View In Browser Not Same As In Designer?

Mar 5, 2011

I'm just getting started in and am building a site. I made a change to a style sheet to change the color of the links in my menu control on my master page. It looks great in the designer and is just the way I want it. Although, if I view default.aspx in the browser it is back to how it was before I made the change. Can anyone give me some suggestions on places to look to figure out why it isn't right in the browser?

MVC :: Error In View While Looping Trough IQueryable(of T) Entity From A SQL View?

Jan 18, 2011

when I'm building a menu in a view I get following error when code reaches <% Next item%> :

System.InvalidOperationException was unhandled by user code

Message=The value of a property that is part of an object's key does not match the corresponding property value stored in the ObjectContext. This can occur if properties that are part of the key return inconsistent or incorrect values or if DetectChanges
is not called after changes are made to a property that is part of the key.


My view: (its a userview)


My Model

My Datasource

I use this way of looping frequent the only thing is that this is that this entity has a view as source and not a table, so I think it has to be related with that.

How To View/review Excel File In Browser

Oct 20, 2010

I can place an Excel file in the root directory, use Browse and view an xlsx, xlsm or any other Excel file and it (sometimes) pops up in a browser window with no option to save or do anything other than view the Excel document (you can type in the cells and it gives you the option to save if there are any changes). I'm trying to find out how to do that exact thing client-side.

We have a server that allows a client to upload an Excel file and we want them to be able to review it only. If there is a way to bypass the Open message box that pops, that would be ideal, but just getting it to display in a separate, small browser window would be just what the doctor ordered. The Excel files are varied so the content is always different and not necessarily formatted the same. That removes the ability to go with named ranges and definitions.

Currently with the code we have, users can press a view button to review the file they uploaded for errors but it opens up the full version of Excel and then throws errors because it tries to force a save to a temp file. Not exactly ideal and very confusing to the user. I don't habve the exact code available to me at the moment, but I'm hoping that someone can point me in the right direction.

Visual Studio :: View In Browser Goes To Different Ports?

Jun 29, 2010

I have a solution CPortal created in Visual Studio 2010. It has two Projects (CPporal and Login). If I right click the Login project folder and select 'View in Browser' It opens in IE as http://localhost:4558/Login/. If I rightclick the CPortal folder and select 'View in Browser it opens as http://localhost:1807/CPortal/. Please note the change in port number.

I am facing problem because, after I get myself authorized on the Login, it is is supposed to redirect me to CPortal, which it does, but uses the same port number that Login opened with. i.e. It redirects me to http://localhost:4558/CPortal/ and gives 404 file not found error. How do I make Visual Studio 2010 to use the same port number for both (all) projects so that this problem does not occur.
