The normal step is to use the process report method in the RDP class to populate the tables
but how do we modify this via an extension class.....
- Create the extension class
- Declare public variable for table to be added as new datasource for your report.
- Create a method to return the additional table content - decorated with SSRSReportDataSetAttribute as per normal.
- Create a public method to populate this table. - i.e. do what you would normally do in the process report method.
