For binding to a ListBox you can use:

ListBox1.DataSource = System.Web.Security.Roles.GetUsersInRole("Role_Name");
ListBox1.DataBind();

Roles.GetUsersInRole returns a string[] of user names in a role. If you really want the MembershipUser objects, you can use:

var list = Roles.GetUsersInRole("roleName").Select(Membership.GetUser).ToList()

Of course, this is performance intensive as it hits the database once for every user.

If you are willing to give up provider-independence, you can query the underlying database directly and perform a join on the database server to get all users in a specific role.

Use the RoleProvider class http://msdn.microsoft.com/en-us/library/system.web.security.roleprovider.aspx

it has a FindUsersInRole method
