Alternatively you can put the entire link into databinding:

<asp:ListView ID="ListView1" runat="server">
<LayoutTemplate>
    <asp:PlaceHolder ID="itemPlaceholder" runat="server"></asp:PlaceHolder>
</LayoutTemplate>
<ItemTemplate>
    <h2><%#Eval("NC_Title") %></h2>
    <%#Eval("NC_StartDate") %>
    <p><%#Eval("NC_Abstract") %></p>
    <%# !string.IsNullOrEmpty(Eval("NC_Description") as string) ? "<a href=\"\">Read more...</a>" : string.Empty %>
</ItemTemplate>
</asp:ListView>
