dear all,
how to know some fields were modified by user?
list bellow my project:
components: DataGridView,DataSet
when user change the DataGridView colmons field value,we can use
Dataset.Getchanges.tables[0] to list current record was modified.
but I can't know which fields were edited,only know the user edit the row.
even though I can't know it if a new record or edited record.
thanks all!!!

Keep track of which cell was entered when it is entered.

Each DataRow will keep track of the original values in the columns.
You need compare to the original value with the current value to
determine whether a column has been modified.

Listen to

public event DataRowChangeEventHandler RowChanged;

public event DataRowChangeEventHandler RowChanging;

event of data table and handle the diffrences of the row data instances.
