DataView Rowfilter

I am loosing my mind on this :)

I have a dataview and I am doing something like this
dv = ds.Tables(0).DefaultView
At this point if I dodv.Table.Rows.Count It returns 5

If I dodv.RowFilter =" pos = '1' " where pos is one one of the column

dv.Table.Rows.Count returns 5 when it should have returned 2 .There are 2 records with pos=1

I am not sure what Iam doing wrong

ANy help is appreciated.

thanks
