How to use conditional Eval inside Repeater control?

How to use conditional Eval inside Repeater control in this case:

if Actions.ShowDates(Eval("DatesAsPeriod").ToString(), Eval("DateList").ToString().Length) > 0
then show this:
    <a href="Details.aspx?ActionID=<%# Eval("ID") %>"><%# Eval("Artist") %></a>
else show this:
    <%# Eval("Artist") %>

You have to wrap if statements in code tags:

<% if (Actions.ShowDates(Eval("DatesAsPeriod").ToString(), Eval("DateList").ToString().Length) > 0)
   {
%>
    <a href="Details.aspx?ActionID=<%# Eval("ID") %>"><%# Eval("Artist") %></a>
<%
   }
   else
   {
%>
   <%# Eval("Artist") %>
<%
   }
%>

Inside a repeater, you should be able to use this:

<%# (Actions.ShowDates(Eval("DatesAsPeriod").ToString(), Eval("DateList").ToString()).Length > 0) ? "<a href="Details.aspx?ActionID='" + Eval("ID") + "'>" + Eval("Artist") + "</a>" : Eval("Artist") %>

You can wrap it into placeholders

<asp:PlaceHolder runat="server" 
  Visible='<%# Actions.ShowDates(Eval("DatesAsPeriod").ToString(), Eval("DateList").ToString().Length) > 0 %>'>
  <a href="Details.aspx?ActionID=<%# Eval("ID") %>"><%# Eval("Artist") %></a> 
</asp:PlaceHolder>
<asp:PlaceHolder runat="server"
  Visible='<%# Actions.ShowDates(Eval("DatesAsPeriod").ToString(), Eval("DateList").ToString().Length) == 0 %>'>
  <%# Eval("Artist") %>
</asp:PlaceHolder>
