Multiple sortable headers(linkbuttons) per column?

[tonicvodka]

Hi all!

I've constructed a datagrid with one template column, this so I can
format the data as I please. But it retrieves data from several
database columns.

I want to be able to sort on each of these several database columns, so
on the template column header I have several linkbuttons, wanting each
to pass a different SortExpression.

I tried setting sortexpression in the link buttons like:

<asp:LinkButton id="lnkDate" CommandName="sort" SortExpression="Date"
runat="server">Date</asp:LinkButton>

But as expected, SortExpression isn't passed along.


Is there a way to do this with the built in SortCommand?

Thanks for any suggestions,
Niclas
