Tony,

I struggled with this until I got the book "Crystal Reports .NET Programming" by Brian Bischof. You can get more information at http://www.crystalreportsbook.com/ and the book can also be found on Amazon.

In this book, he lays out the steps:

Report Creation
1. Define the dataset schema file
2. Build the report using the dataset schema file as the data source

Running the Report
3. Populate the dataset
4. Bind the dataset to the report

He gives some very good sample code and explains each of the steps in detail. It took me a day or so to work through it, but this solves the problem of working with datasets.

Kind Regards,

Mat
