Assigning a CSS class to a client-side hyperlink in the back-end code

I've been given a task involving a list of links:

<ul>
    <li><a href="#">Aktuel</a></li>
    <li><a href="#">Business</a></li>
    <li><a href="#">Common</a></li>
    <li><a href="#">Extras</a></li>
</ul>

My job is to add a CSS class to one of the links programmatically using C# in the codebehind. The desired outcome should look like this:

....
<li><a href="#" class="active">Business</a></li>
....

Can anyone advise me on which lifecycle event I should use and how to accomplish this?

Please note that I am not allowed to make any changes to the HTML design.

Thank you in advance.

Answer №1

To achieve the desired functionality, you can utilize ClientScript.RegisterStartupScript in the CodeBehind file to execute a jQuery script.

Here is a complete solution that includes the necessary ASP.NET code:

string jsScript = "$(function () { $(\"a:contains('Aktuel')\").addClass(\"active\"); });";

ClientScript.RegisterStartupScript(typeof(Page), "uniqueIdentifier", jsScript, true);

You can see it in action here (excluding the ASP.NET component):
