Determining whether DataRow values have changed

[GazzaJ]

I have an application with a strongly typed Dataset which I populate and then transform the rows in the DataTable into objects used in my application. The application then updates the objects and I call code to update the appropriate DataRows before submitting the updates to the table. I originally wrote the method to update the DataRow to update each column in the row using the value in the object passed in. This however causes the RowState of the DataRow to change from Unchanged to Modified even if the value has not changed. Therefore I have logic to check the values in the DataRow with the value in the object and only update if there is a change, this logic incorporates checking for null values also. Is there any method of getting the DataRow to do this automatically?
