[OT]kinda. Filter DataView based on Parameter

I am trying to filter a dataView based on a few items and cannot figure out how to input a parameter.

I have this :

dtvJobHead.RowFilter = "Checkbox02 = True And JobClosed = False And JobComplete = False "
ugdEpiCustom1.DataSource = dtvJobHead

But I am having a heck of a time getting the syntax to also base the RowFilter on a parameter in addition to static string values.
