For example: <% # databinder. (container. dataitem, "classname") %>
<Asp: datalist id = "DL" runat = "server">
<Itemtemplate> <% # databinder. (container. dataitem, "classname") %>
</Itemtemplate>
</ASP: datalist> </TD>

<TD Height = "20">
<Div align = "center"> category: </div>
</TD>
<TD Height = "9"> & nbsp;
<% Function (); %>
</TD>
</Tr>

<% # Is a binding expression, that is, you must use the databind () method to use it <% #
