Sorting via parameters in SQL Server Reporting Services

In SQL Server Reporting Services (SSRS) there are two different methods for a user to sort their reports after they have been generated. Other folks have done a superb job of explaining each method, so I’ll just point you to their sites:

The user can interactively sort on a header textbox by just setting the “interactive sort” properties:

You can also sort using standard report parameters:
