XtraReports allows you to print multiple subreports side-by-side within one report. Subreports can be completely independent from each other, and can even be bound to their own datasource.
In this demo, a report is constructed by two identical subreports that are designed to show employee information. You can control which employee is to be shown on each report side, and this employee's name is passed to a subreport as a parameter to filter its data.
