    <p>A very direct way to do this would be to add a parameter to the link in each item in the list. So instead of something like this:</p> <pre><code>&lt;a href="detailspage.aspx"&gt;View Details&lt;/a&gt; </code></pre> <p>You'd have something like this:</p> <pre><code>&lt;a href="detailspage.aspx?id=123"&gt;View Details&lt;/a&gt; </code></pre> <p>Naturally, each <code>id</code> would be different for each row. How you populate that depends on how you populate the listview.</p> <p>Then you'd have a single <code>detailspage.aspx</code> (or whatever you call it) which would look for an <code>id</code> parameter (check the <code>Request.QueryString["id"]</code> value in <code>Page_Load</code> for web forms, or have it as a method parameter in MVC) and use that value to fetch the record from the database and display the details.</p> <p>One thing that's very much worth noting in this case is the need to validate that input before sending it to a database. You didn't specify how you're accessing the database, so I can only guess. But, regardless of your data access methodology, the <em>first</em> thing you want to do with that <code>id</code> value on the details page is to make sure it's a valid value to use for selecting data.</p> <p>For example, if the identifier in the database is an integer, you'll want to try to parse the value into an actual integer variable (if it's a string by default, which it would be from <code>Request.QueryString</code>), returning an error to the page if that fails. Or if it's a GUID, same process. Basically, you want to do whatever you can to ensure that the value is safe for the database before even connecting to the database.</p> <p>More details on SQL injection vulnerabilities <a href="http://en.wikipedia.org/wiki/SQL_injection" rel="nofollow">here</a>.</p>

    1. COHey David, thanks for you help. I used the Request.QueryString in my second page to access the database and pull the details to display on my second page. However, I was only able to do that from by setting the id=2. I was wondering if you would also know how to set the id for each item in a listview. What would you recommend? Thanks for all the help you've been.

    2. CO@cbenson: Depends on how you're currently populating the listiew. Can you update the question to include the list view code (both on the page and in the code-behind), as well as the shape of the data being used to populate it? Then just mention in a comment here so I'll know there's an update.

    3. COHey David, I got it work the way I wanted with few minor adjustments: 1) changed stored procedure to access the id as well, so my listview now as the list of names and their id associated with them (i didn't have that before) 2) i used databinder and stringquery **bold**<asp:Hyperlink runat= "server" Text='<%# DataBinder.Eval(Container.DataItem,"Results")%>' NavigateUrl='<%# "Testpage2.aspx?id=" + DataBinder.Eval (Container.DataItem,"ID")%>' ID="Link2" />**bold** thanks for all your help

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
