Does anyone know a nice way to filter a flexgrid?

I have been searching the web and have found work around suggestions, - the best was probably setting the rowheight = 0 - but that would require looping through each row.

In my case, I have an unbound flexgrid that includes a column that can equal one of two values. Is there a setting that can be used to make the grid show only the rows with one of these values?

Thank you.
