DataViews, reference or copy?

[James]

I have a DataView that I bind to a grid. I stored the DataView in Session
memory and then use a popup to display/filter some of the data. At the
simple level, I do the following on the pop-up:

Dim dv As New DataView

dv = CType(Session("dvResults"), DataView)

<more code here>

If I delete a row from this DataView, will it affect the DataView in Session
memory, which would ultimately affect my other page, or is this just a copy
of the data that I can manipulate however I'd like without affecting
anything else?
