Datalist hyperlink border

[manikal]

I have problem with datalist control that add ugly border around my
thumbnail when I wrap hyperlink tag around that image.

Here is my code:

<asp:DataList ID="DataList1" runat="server" RepeatColumns=" 3"
RepeatDirection ="Horizontal " CellSpacing="5" border="0">
<ItemTemplate >
<a href="#" class="noborder "
onclick="window .open('popup.as px?img=images<% =category%><%#
DataBinder.Eval (Container.Data Item, "Name") %>','nwwin',
'toolbar=0,loca tion=0,director ies=0,status=0, menubar=no,scro llbars=yes,resi zable=yes,width =1024,height=76 8');">
<img src="<%=appPath %>/images/<%=category%>th umbnails/<%#
DataBinder.Eval (Container.Data Item, "Name") %>" /></a>
</ItemTemplate>
</asp:DataList>

Advice please,
