Answer 1

You can do a version of this by sorting your AdvancedDataGrid's dataProvider in reverse order of the scheme you describe. It will be a series of sort operations. First sort by date, then product, then contact-person, then finally sorting on company. If your AdvancedDataGrid has sortable columns, however, user interaction could immediately mess this up.
