I'm developing a web site with asp.net on localhost,I'm beginner.I wrote a login page and it works well. However when I click a link,the server can't load the page and gives this error:A network-related or instance-specific error occurred while establishing a connection to SQL Server.The server was not found or was not accessible.Verify that the instance name is correct and that SQL Server is configured to allow remote connections.(provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
When i'm trying to debug or view pages of my site in browser asp.net dev server doesn't turns on pages automatically and when im trying to go by url it throws me an error See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.

How to display pages from the last to the first number in DataPager? Is there any tricks or I can do this with standart properties? I use Repeater with LinqDataSource control.
I have created one crystal report which has one Group name field too. My Crystal report has 3 pages. But the Group Name field is displayed only in the first page. I want to display the Group Name field in the next pages also.
During debug builds I would like to show the duration it took, server side, to generate a page in the pages footer.
So for example if a page takes 250ms server side I would like that displayed in the footer, in debug builds. How can I achieve this in an ASP.NET MVC project?
I am working on the migration of the server. Our new server is Windows server 2008 with IIS7.0 I have a great difficulty in browsing the pages hosted in virtual directories. I have followed the proper steps of creating a virtual directories and converting them into applications. But when i try to browsing the pages of the virtual directory, i get the 404 error. Note: The .Net Framework 4.0 is installed on the server and the web applications which i am trying to configure in the virtual directories are developed in Visual Studio 3.0. Even the http://localhost also don't work.
I have created one crystal report which has one Group name field too. My Crystal report has 3 pages. But the Group Name field is displayed only in the first page. I want to display the Group Name field in the next pages also.I am using Crystal Reports 2008.
I am trying to figure out why it won't display the other results when I click on the second and third links created by enabling the paging option the gridview control. it wasn't displaying properly.. also it may not make a lot of sense.. I'm a PHP programmer... I'm learning asp.net as part of a class and we're instructed to use the drag-and-drop method so forgive me, my asp.net skills are lacking and I am having a hard time learning it. Anyway I'm reposting the current code.. hopefully it will display properly this time. Here's the code for default2.aspx..
I am using VS2008 and want to display a login page with a background image. If I add the image to the page's body and name the page login1.aspx, it displays fine. However, when I change the name to login.aspx, I can see the background in design mode, but the background image does not display when run (debug or otherwise).
I try the same thing using a div or asp:panel and get the same results. I read a post where someone else was having similar problems; however, no answer was given other than blaming VS2005.
I reviewed the previous article on a similiar subject, but it was more for C+. I have an Access db feeding a Gridview control, with the defaults of 10 records per page. I know there are more then 10 records for the information I searching on, and pages 2 & 3 are listed in the 'paging' feature in the header. By the way, my page is results.aspx.
Clicking on page 2 results in no additional results being displayed. I understand a little from the other post, that Gridview tied to Access will not automatically show results past page 1, without some additional coding changes.
I am debating between 2 scenarios for handling the display of a product catalog for a website redesign I am performing. I will be using the IIRF isapi filter to perform the rewriting for an asp.net website.
Here is what the urls will look like
[URL]
[URL]
[URL]
etc...
There will be a total of 8 or 9 product group pages
Scenario 1: I have these pages rewrite to one general purpose page that will look something like this:
[URL]
Then I decide which catalog to display with a switch/case based on the querystring. All of the code for displaying the catalogs would be based off of one page.
Scenario 2: I create a separate page for processing each different catalog page. The rewriting would look something like this then:
[URL]
Then each catalog page would have it's own .aspx to handle the processing and display of that group of items.
I m very new in VS (ASP.NET) and using C# in code behind file. I want to define global variables to use in whole application. EXAMPLE

i have encountered a problem on how to load the database images to be display in the Image content in the web pages. I am currently using an Access database with a table "Images" and there are 4 columns in it. "ImageID", "ImageDescription","ImageofPicture","Description". Below is my code: Words highlighted in bold is where the problem occurs. No image is display in the Image box but theres a red cross at the top left. Image description is displaying fine in the textboxes

I just upgraded to 2010 and converted my VS 2008 ASP.NET web application. There were no conversion errors and everything displays in the Design mode correctly but when I try to View in Browser or debug the site won't display. I just get a blank page untitled page displayed.

I need the solution even the user is click Server1.com it need to display Server2.com page but the URL wont be change? Is it possible with Asp.net ?hen browse www.server1.com need to display the www.serber2.com page URL of the browser sholud be www.server1.com.. this is my question?
I've been writing an app using the awesome new Razor view engine and for the most part, things have been great.
One issue I keep running into, however, is that if I should happen to write invalid code, such as referencing a null property or even a non existent property, rather than throwing an error, something happens in the background that causes the browser to wait and wait and wait and if I do not cancel the browser's request quick enough, IIS will simply hang.
It seems as if it enters some sort of loop. CPU usage goes up (though not terribly high) and restarting IIS via either GUI or iisreset command seems to take abnormally long (presumably while it waits for the process to safely shutdown).
This also happens for other invalid code scenarios such as failing to close a code block with a closing brace.
