How can you identify whether any changes are made to the DataSet object since the time it was last loaded?

Answer»

The DataSet object has two methods to TRACK down the CHANGES:

GetChanges(): It RETURNS the DataSet object that has been CHANGED since it was loaded or since the execution of the AcceptChanges() method.
HasChanges(): It indicates if any modifications were made since from the time the DataSet object was loaded or after a method call to the AcceptChanges() was made.

Use the RejectChanges() method, if you want to reverse the entire changes since from the time the DataSet object was loaded.
