Video: Attaching external CSS files

The first step in creating a Cascading Style Sheet visual design in an ASP.NET website is to create and attach an external style sheet file. External style sheet files are simple text files that are placed in the Websites Root folder or in a sub-folder of the root. They always have a file extension of .css. The task of actually creating the style sheet file can be done either as pure text or pure coding exercise or it can done using Visual Web Developer tools. I'm going to be working with a website that already has a number of files in it. Go to the Visual Web Developer menu and select File > Open Web Site.

Attaching external CSS files

The first step in creating a Cascading Style Sheet visual design in an ASP.NET website is to create and attach an external style sheet file. External style sheet files are simple text files that are placed in the Websites Root folder or in a sub-folder of the root. They always have a file extension of .css. The task of actually creating the style sheet file can be done either as pure text or pure coding exercise or it can done using Visual Web Developer tools. I'm going to be working with a website that already has a number of files in it. Go to the Visual Web Developer menu and select File > Open Web Site.

Navigate to the VisualDesign folder under Chapter06 VisualDesign and click Open. In this website, there are four primary pages: Default.aspx, which is the homepage of the website, and then three other pages, Authors, Publishers and Titles. There is a server control called Header.ascx, which is used by all four pages, which contains a number of hyperlinks wrapped inside ASP panel components and there is also a beginning style sheet file called styles.css.

The style.css file has selectors for the body, table and anchor elements and a pseudo selector called a:hover that affect anchor tags when the mouse is hovering over them. If you take a look at the Default.aspx, you will see that currently the page doesn't have any links to the style sheet file and if you test the page in the web browser, you will see that the styles in the styles.css file are not being applied right now. You are seeing the default fonts and colors applied by the browser. So here is how you attach the external style sheet file to a page. Go to Default.aspx and look at the page in Design view, then over on the left, click on Manage Styles. You will see when you click the Manage Styles tab that the Manage Styles window slides out from the left. Now because we'll be using styles extensively, click the Pin icon, which will pin the panel open and also adjust the design area, so we can see both at the same time.

Now click the Attach Style Sheet link. From there, look in the Root folder and you will find the file styles.css and click OK. You will see in Design view that the fonts change immediately reflecting the settings in the Style Sheet. Now try browsing the page again in the browser. Select Debug > Start Without Debugging, look at the page in the browser and you will see it has a very different look and feel. The font settings from styles.css have been applied and if you move the cursor over the anchor tags at the top, you will see that the menu reflects the a:hover pseudo selector that was declared in the external style sheet.

If you open the other files, Publishers. aspx, Authors.aspx and Titles.aspx, you will see that this link has already been created in these other pages. So that from this point onward, any changes that you make in the external style sheet file, styles.css, will be applied to all of the pages in the entire website. Once you have created this link, it makes it very easy to create side like design settings that are created and defined in CSS and then used in all pages of the website.

Q: When trying to create a new database, after pasting the text into the SQL Management Suite and executing the query, the database is not created and the following message appears: 

Database 'mybookstore' does not exist. Make sure that the name is entered correctly

What is causing this error?
A: The database must be explicitly created before the script is run. Start by right-clicking on the Databases item in the left panel, then follow the prompts to create the database. Then retry the query.
Q: I am running into problems installing the latest version of ASP.NET. Has the installation procedure changed since this tutorial was recorded?
A: The installation process for the newest version of ASP.NET and its associated tools is a little different than in ASP.NET 3.5, which was used to record this course. You can download Microsoft Web Platform Installer 2.0 from:
<a href="http://www.microsoft.com/web/downloads/platform.aspx" target="blank">http://www.microsoft.com/web/downloads/platform.aspx</a>
Microsoft Web Platform Installer 2.0 includes everything you need:
ASP.NET 4?
Visual Web Developer 2010?
SQL Server Express
You must have one of the following operating systems:
Windows 7?
Windows Vista?
Windows Vista SP1?
Windows XP SP2+?
Windows Server 2003 SP1+?
Windows Server 2008?
Windows Server 2008 R2
You must have administrator privileges on your computer to run the Web Platform Installer.
Q: This course was updated on 2/13/2013. What changed?
A: Since this course was recorded, Microsoft has released both ASP.NET 4.5, the latest version of the server-side web application server, and Visual Studio Express 2012 for Web (the successor product to Visual Web Developer). Both have been adapted to work on Windows 8. There will be some visual changes and some functional changes, but most of the server-side code shown in the course is the same. This update provides a map for those working with the latest software so they can navigate their way through the course.

In particular, we added <em>What's new</em> movies for both ASP.NET 4 and 4.5, a movie explaining the significance of the update, a movie on installing SQL Server Express 2012, and one on exporting database scripts in SQL Server Management Studio 2012, as well as updates to visuals throughout the course.
Q: In the chapter on user authentication, an authentication error results when I try to use the Login component or register a new user. How do I fix this?
A: This is a known error that can occur when using the original release of Visual Studio 2012 Express for Web. Update your copy of Visual Studio for Web to at least maintenance release 1, and then try the exercise again.
