There are many ways to do this. There are some easy and some ugly hacky ones:

Solution 1:
Use a Menu Control. The standard .NET Menu Control has an easy solution to do this. This is the cleanest and fastest solution in my opinion. Have a look at this post. Maby it'll help you if you choose this solution.

Solution 2:
You coud use some sort of javascript to highlight the current item. jQuery would make that easier if you dont want to write everything by yourself. For this solution have a look at this page. It's outdated but still effective.

Solution 3:
This is kinda ugly solution and you can do that in many different ways: You could change the <a> elements to HyperLink controls and set some sort of session or cookie when you click on them. When set you could change the style based on the value the cookie has.

There are even more ways you could solve this but I think the first two solutions will help you.

For Solution 3, you can refer the second post - Highlighting active link when using Masterpage[^].

Quote:

Each Hyperlink control has an id. Style the link with that id on the page.

E.g., for the page linked to by control id="HyperLink1", create a style on that page that gives a#HyperLink1, say, bold red text. Repeat on the other pages, creating styles on those pages that style the id of their hyperlink.

This doesn't rely on knowing if the link is active, simply on knowing what page you are on, and which link in the menu is for that page.

Try this...:)

How to set active class to the current page link if your navigation menu is in a master page ?

Assuming that your menu structure is as shown below in the (Master.aspx) file :

<ul>    
     <li><a href="Dash.aspx">Dashboard</a></li>    
     <li><a href="Tests.aspx">Test</a></li>    
     <li><a href="Report.aspx">Report</a></li>    
</ul>

Start by assigning a unique (id) to each element and add the key (runat="server") to each. so your markup would look like this

<ul>      
     <li id="dashlink" runat="server"><a href="Dash.aspx">Dashboard</a></li>      
     <li id="testslink" runat="server"><a href="Tests.aspx">Test</a></li>      
     <li id="reportlink" runat="server"><a href="Report.aspx">Report</a></li>      
</ul>

Finally in the code-behinde of the Master Page, add the following to the (Page_load) function

protected void Page_Load(object sender, EventArgs e)  
{  
  
    String activepage = Request.RawUrl;  
    if (activepage.Contains("Dash.aspx"))  
    {  
        dashlink.Attributes.Add("class", "active");  
    }  
    else if (activepage.Contains("Tests.aspx"))  
    {  
       testslink.Attributes.Add("class", "active");  
    }  
    else if (activepage.Contains("Report.aspx"))  
    {  
       reportlink.Attributes.Add("class", "active");  
    }  
  
}

Enjoy!
