Crete an eval if in asp.net

I am trying to create an If that has the condition that, if the eval value is 0 the div wont appear.

<%@ if (DataBinder.Eval(Container.DataItem, "Desconto").ToString() != "0"){ %>
    <p><span class="oldprice"><%# Eval("Preço") %>€</span> <i class="newprice item_price"><%# ((decimal)Eval("Preço")-(decimal)Eval("Preço")*((decimal)(int)Eval("Desconto")/100)).ToString("N2") %></i>€</p>
<%@ } %>

But i am not figuring out the syntax to create the eval, it aways ends up as some error.

Thanks in advance for reply.

Use # instead of @ - 

<%# if (DataBinder.Eval(Container.DataItem, "Desconto").ToString() != "0"){ %>
    <p><span class="oldprice"><%# Eval("Preço") %>€</span> <i class="newprice item_price"><%# ((decimal)Eval("Preço")-(decimal)Eval("Preço")*((decimal)(int)Eval("Desconto")/100)).ToString("N2") %></i>€</p>
<% } %>

You can wrap the code inside a Panel and set the Visible based on the value of the Eval.

<asp:Panel ID="Panel1" runat="server" Visible='<%# Eval("Desconto").ToString() != "0" %>'>
    content
</asp:Panel>

Or use a ternary operator if you do not want an extra Panel

<div style="display:<%# Eval("Desconto").ToString() != "0" ? "block" : "none" %>">
    content
</div>
