SQL Reporting :: Passing Parameter In Subreport From The Parent Record?

I am creating a report using sql reporting services (.rdlc) in asp.net web application. I am displaying master records using List because I need to display one record in one page. In each page now I want to display the child records in a table inside the same List control.

For example: In mater records there will be Department Name, Department Location, Department Zip. In child records there will be Employee Name, Employee Id, Employee Salary, Employee Start Date. There is a link between Dapartment and Employee table by Department Id. I want to display one department record in one page and the all employee of that department in same page in a table. And next page of the report will have other department record and respective employees in a table.

I am being able to display Department records in each page but not being able to display Employees records in a table for particular Department Id. For this I used List control.
