Hello experts,

I used to program in Delphi and used TDataSet.State to check on the
status of a database operation (Insert, Update, Delete, Browse). Now
that I'm into C#, I would like to know if there is a property or class
that exists and has this kind of behavior.

Many thanks in advance.

Cheers,

Benj

I'm not familiar with Delphi, but the DataSet has a collection of Tables,
and each DataTable has a collection of Rows, and each DataRow has a property
called RowState which tells you if it is Added, Deleted, Modified or
Unchanged. Is this what you wanted to find?

As Alberto indicated, in addition to the DataRow, DataTables support a series
of events you can subscribe to. Here's the url to the MSDN Documentation page
listing them:
