Gridview Customizing Colums with EVAL

So in a gridview you want to combine 2 fields together in presenting the output, or you want to make it appears as


<columns>
<asp:templatefield headertext="No">
<itemtemplate>
<%=countr++%> <%# Eval("Title") %>
</itemtemplate>
</asp:templatefield></columns>



Ensure its <%# and not <%=


Another nicer way to do it:-

                <asp:TemplateField HeaderText="Title">
                <ItemTemplate>
                <%# String.Format("<a href='viewTaskDetail.aspx?id={0}'>{1}</a>",Eval("ID"),Eval("Title")) %>
               
               
                </ItemTemplate>
                </asp:TemplateField>
