Conditional format table without codebehind

I inherited a project with a giant table in an aspx page that has a TON of inline code. Now I need to conditionally style a row based on the value of a textbox in the table. Unfortunately, I can't add a "runat=Server" tag to the table row because of all the embedded <% %> tags. I just need to apply the style to this row. I know all this embedded stuff needs to move to the code behind. I didn't write this - I just need to get this one small thing fixed.

        <ajax:Accordion ID="Accordion1" runat="server" FadeTransitions="False"  
            SelectedIndex="0" HeaderCssClass="accordionHeader" ContentCssClass="accordionContent">
                <HeaderTemplate>
                    <div style="height:20px;">&nbsp;</div>
                    <table class="cart" >
                        <tbody>
                        <ItemTemplate>      
                                <tr class="row I need to style  " >                                   
                                <%if (Isvalid) { %>.... tons more tags like this in the td sections.

Any advice?

You can do a switch in the tr class:
   <ItemTemplate>       
       <tr class="<? switch(Eval("datafield you based for style"){case ... ...}?>" >                                 
            <%if (Isvalid) { %>.... tons more tags like this in the td sections. 
            ...

After walking away for a bit, I tried putting an asp panel around it and then setting visibility of the panel in the code behind. Working perfectly now. Accepting switch because that would have worked as well.
