Geoff,
Didn't I answer this one the other day?
You can only create DataView from a DataTable itself or
DataRowView.CreateChildView, the second requires a DataRelation defined.
With effort you can build a row filter based on values in the first view,
however I suspect that will be more trouble then its worth.
I would simply use the first view and manually select the rows I was
interested in.
Hope this helps

Hi
What is the best way for me to create a dataview based on a subset of
another dataview? That is, I have one dataview, say FirstDataView, which
contains some rows which I want in another dataview, say SecondDataView.
What is the most efficient way to accomplish this?
Ta
Geoff
