I found a way to insert an <%#Eval %> statement into the attribute I wanted to change. I point it towards the correct property of the rssobject, and its working.
<Columns>
<asp:TemplateField>
<ItemTemplate>
<blockquote>
<strong><a href='<%#Eval("Link")%>'>
<%#Eval("NewsDesc")%></a></strong>
<br />
<span class="italic">
<%#Eval("NewsDate")%></span>
</blockquote>
</ItemTemplate>
</asp:TemplateField>
</Columns>
