display columns from 2 tables in datalist

[Joe Van Meer]

Hi,

I have a datalist that is bound to a dataset that contains 3 tables and
relations are created between these tables. My question is how to reference
data from columns in the second table in my datalist in my itemtemplate.

Do I use the same notation as this? Or is there something I am missing?

<%#Container.DataItem("SECONDTABLEFIELD")%>

Or would it be something like:

<%# mydataset.Tables(1).Columns(MyColumn) %>

Thx in advance, Joe
