DataList Databinding Question...

[Sal]

Hello All,
Is it possible to databind Header Template for a datalist ?
for example for binding to an item template I can use the following
construct:
<ItemTemplate>
<%# DataBinder.Eval(Container.DataItem, "ProductID") %>
</ItemTemplate>

In trying to databind the Header the following construct did not work:

<HeaderTemplate>

<%# DataBinder.Eval(Container.DataItem, "CategoryID") %>

</HeaderTemplate>

Is there a way to accomplish this with one trip to the server? i.e. binding
both header and item to the same datasource and different fields?

Any help will be greatly appreciated
