Filter Datagrid not the source?

Question

HI I have an array of Objects and two datagrdid that
represent two different views of that array. One shows all stock
orders and the other shows stock orders for the financial market I
have in view. When I filter one datagrid by applying the filter to
the source both datagrids get filtered as I expected. Do i need to
create two arrays to bind to the datagrids that get their data from
the original array and if so how will this affected binding when a
new record is added to the original array will the other arrays
automatically update and thus update the datagrids.

When I've done something like this, I've used one array to
hold the data and two arrayCollections built from the array. Bind
the arrayCollections to the grids, and apply filters and refesh
each collection.
When the data changes in the array, I think you have to
refresh both collections.
