Hello,
Somebody ever tried to create a "GetChanges" method in a custom collection
implementation (CollectionBase)?
The goal is to provide the same behavior of the DataSet.GetChanges method to
update the underlying datasource.
TIA.
 
Hi Olivier,

In my opinion, we cannot implement a GetChanges method in CollectionBase,
as it does in DataSet. Because in DataSet, each DataRow in it has a
property named RowState. The GetChanges method looks for changes according
to the RowState value. All the rows with the value of Added, Modified and
Deleted are changed rows, thus the method can build a collection of changed
rows.
