Gridview Databinding help

I have a databind that returns all roles, the problem is would like to customize this control so that the actual role has all other columns included for example roleid, rolename, roledate etc.

the following only returns all roles and the header name is "item"
gvRoles.DataSource = System.Web.Security.Roles.GetAllRoles
gvRoles.DataBind()

    <asp:GridView ID="gvRoles" runat="server" AutoGenerateColumns="true" AutoGenerateDeleteButton="true" AutoGenerateEditButton="true" AutoGenerateSelectButton="true">
                        </asp:GridView>

 SqlDataAdapter Adapter = new SqlDataAdapter(Command);
            DataSet RolesDS = new DataSet();
            try
            {
                SqlConn.Open();
                Adapter.Fill(RolesDS);
                int i = 0;
                roles = new string[RolesDS.Tables[0].Rows.Count];
                foreach (DataRow role in RolesDS.Tables[0].Rows)
                {
                    roles[i] = role["RoleNames"].ToString();
                    i++;
                }
            }
