I am looking to apply a rowfilter with a series of primary key values to a
dataview.

The data is populated from and xml file.

I am pulling the list of primary key values from an html <select><option>
list and returning comma separated pk values.

Doing something like rowfilter = "pk=a or pk=b or pk=c" seems a little long
winded.

Is there a more effective way that I could be constructing my rowfilter. I
haven't found a source that shows all the valid constructs that can be used
in a rowfilter.

TIA,

Chris
