Creating a gridview to allow editing of current users

I finally got membership and roles setup and seems to be working.
I have setup a page to allow the creation of a user and editing of roles for a user.
I would like to setup a page with a gridview that displays all users and what roles they are assigned. I remember running across someone else that was looking to do the same thing, but cant find it. Not sure if it was in this forum or online somewhere else.
But i found that i can use the  aspnet_Membership_GetAllUsers procedure in my db to get all the users, but how can i add the roles to each person and possibly setup the gridview so that each role they have, is displayed on their row in the gridview
So i would like to see something like this maybe more data displayed depending on the client request.
