title: dependent parameter does not refresh after first parameter is input
body: <p>My SSRS report (2008 version) has two parameters. The first is a textbox receiving input for Supervisor' userid. The second is a drop-down which depends on the first parameter to show the all the staff name working under the supervisor. My questions is how the second parameter can refresh automatically after I input the first parameter in the textbox. Do I need a hidden parameter?</p>
