Assembly: System.Data (in System.Data.dll)
DataRow objects contained by the DataSet can each be set into edit mode by invoking the DataRow.BeginEdit method. After invoking the DataRow.EndEdit method, changes can be rejected by calling the DataTable.RejectChanges on the DataTable to which the DataRow objects belong.
When the DataTable.RejectChanges method is called, any rows still in edit-mode cancel their edits. New rows are removed. Modified and deleted rows return back to their original state (DataRowState.Unchanged).
AcceptChanges and RejectChanges only apply to DataRow related changes (that is, Add, Remove, Delete, and Modify). They are not applicable to schema or structural changes.
