I use DatagridTableStyle to display data from table
WF_Carrier_FreightChart. USers than can add/delete/edit rows in the
Datagrid.
Since the Datagrid's datasource "dCarrierFreight" is just a copy/view of the
table (dataset dFreight.tables(0) ), I need to update the original table to
reflect multiple changes in the Datagrid.
Your help is greatly appreciated.

Bill,
A view is not copy
a
Dim a as datatable = myDataTable is not a copy,
It are both other references to the same table
So how do you copy your table.

Bill,
In the way you tell it, than your datasource is the original table and you
can use that to update, however it can as well be.
mynewtable as datatable = myoldtable.copy
Than you can use mynewtable to update and than you have to decide if you
fill the myoldtable again or merge the mynewtable in it.
It is not an abc sample, so again, tell us first how you copy that table.
Cor
In the original post I included the codes.

Bill,
You are using a shallow copy, what is very hard to manage. It is a copy of
the references pointing to the original objects.
For a DataTable something without sence. Why are you doing that, while the
datatable has so many other posibilities.
Cor
What's the best / better way to handle batch update in this case, please?
Thanks
