ASP.NET VB Listview assign ID to a table row

What I want to do is assign an ID to a table row with value of a ID of the column in question.

To clarify. I have a data table with fields [ID] [Name] [Description], and populate the ListView like this: (I've simplified the code here for clarity)

<asp:ListView ID="MainList" runat="server" DataKeyNames="id">
    <layouttemplate>
        <dl id="header">
            <dd class="rowHeader">Name</dd>
            <dd class="rowHeader">Description</dd>
        </dl>
        <asp:Panel runat="server" ID="itemPlaceholder">
        </asp:Panel>
    </layouttemplate>
    <itemtemplate>
        <dl class="row">
            <dd><%# Eval("name")%></dd>
            <dd><%# Eval("description")%></dd>
        </dl>
    </itemtemplate>
</asp:ListView>

Now, what I tried was to add it like this.

<dl class="row" id='<%# Eval("id")%>'>

and of course it worked, but I need to pass it as a variable because i need to check for something with it. Like so:

<% Dim id as Integer = Eval("id") %>
<dl class="row" id='<%=id %>'>

I got this error:

Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.

And I get it why... the reason why I need this is so I can compare id with a session variable and change rows class accordingly.

Any way to go around this?

You should be able to do the same type of logic in your class attribute:

<dl class="row" id='<%# Eval("id")%>' class='<%= Eval("id") == Session["myValue"] ? "someCssClass" : "otherCssClass" %>'>

I think this should work.
