dropdownlist in Formview with datasource - setting selected value from session variable

[Jason]

I know that in the codebehind I can set the selected value of a
dropdownlist in a formview using findcontrol and
control.selectedvalue=session("whatever")..

But is there a way to set the selected value for a dropdown, that has
datasourceid to a session variable all in the markup? If so how and
where?, Maybe with inline code ? with somethign like
<%response.write(session("x"))%> or maybe set the selected value via
the sql with a param for the session variable? if so, how?
