从数据列表（C#/asp.net）修改复选框

我正在尝试修改此asp.net/C代码。该页面允许管理员添加用户，并从复选框列表中选择该用户将具有的角色。有11个复选框，旁边有角色可供选择。我想整理这些复选框。我想把11个复选框分为3组CMS、LMS和Admin，以便在页面上将它们分为三个部分。我只想为CMS组选择一个复选框。CMS组可以是一个下拉框，如果这会使它更容易。而且，当用户将鼠标悬停在这些角色上时，所有这些角色都必须有工具提示

您将在代码中看到，复选框是使用userRolesDataSource创建的。此数据源使用名为“GetUserRoles”的方法，该方法有两个参数“username”和“onlyncludeSystemAdminRole”布尔值。选择方法检查用户名是否为系统管理员，如果为真，则排除所有其他角色选择

这是新的GetUserRoles方法：

public List<Pair<string, bool>> GetUserRoles(
            string userName, bool onlyIncludeSystemAdminRole)
    {
        // Return a list of "role name"/"has role" pairs for the given user.
        // If the "onlyIncludeSystemAdminRole" flag is true, only return the
        // "System Admin" role, otherwise return all roles other than
        // "System Admin".
        List<Pair<string, bool>> userRolesList = null;

        if (!onlyIncludeSystemAdminRole)
        {
            string[] allRoles = Roles.GetAllRoles();

            HashSet<string> rolesForUser = null;

            if (!String.IsNullOrWhiteSpace(userName))
            {
                rolesForUser = new HashSet<string>(
                        Roles.GetRolesForUser(userName));
            }

            userRolesList = (from roleName in allRoles
                             where roleName != RoleNames.SYSTEM_ADMIN
                             select new Pair<string, bool>()
                             {
                                 First = roleName,
                                 Second = rolesForUser != null
                                     ? rolesForUser.Contains(roleName)
                                     : false
                             }).ToList();
        }
        else
        {
            userRolesList = new List<Pair<string, bool>>()
            {
                new Pair<string, bool>(
                        RoleNames.SYSTEM_ADMIN,
                        Roles.IsUserInRole(userName, RoleNames.SYSTEM_ADMIN))
            };
        }

        return userRolesList;
    }

公共列表GetUserRoles(
字符串用户名，bool onlyIncludeSystemAdminRole）
{
//返回给定用户的“角色名称”/“具有角色”对列表。
//如果“onlyIncludeSystemAdminRole”标志为true，则仅返回
//“系统管理员”角色，否则返回除
//“系统管理员”。
List userRolesList=null；
if（！onlyIncludeSystemAdminRole）
{
字符串[]allRoles=Roles.GetAllRoles（）；
HashSet rolesForUser=null；
如果（！String.IsNullOrWhiteSpace（用户名））
{
rolesForUser=新哈希集(
Roles.GetRolesForUser（用户名））；
}
userRolesList=（来自allRoles中的roleName）
其中roleName！=RoleNames.SYSTEM\u ADMIN
选择新对（）
{
第一个=roleName，
Second=rolesForUser！=null
？rolesForUser.Contains（roleName）
：错
}).ToList（）；
}
其他的
{
userRolesList=新列表（）
{
新的一对(
RoleNames.SYSTEM_ADMIN，
Roles.IsUserInRole（用户名，RoleNames.SYSTEM\u ADMIN））
};
}
返回用户角色列表；
}

类似的东西仍然需要在所有的复选框上运行

为了解决这个问题，我计划使用类似的方法。可以将角色列表作为参数提供给它。并且，它将排除提供的列表，并每隔一个角色返回一次

public IEnumerable<string> GetRoles(params string[] roleNamesToExclude)
    {
        var query = Uow.Roles
            .AsQueryable()
            .Select(r => r.RoleName);

        if (roleNamesToExclude != null && roleNamesToExclude.Any())
        {
            query = query
                .Where(r => !roleNamesToExclude.Contains(r));
        }

        return query.ToList();
    } 

public IEnumerable GetRoles（参数字符串[]RoleNameStoreExclude）
{
var query=Uow.Roles
.AsQueryable（）
.选择（r=>r.RoleName）；
if（roleNamesToExclude！=null&&roleNamesToExclude.Any（））
{
查询=查询
其中（r=>！roleNamesToExclude.Contains（r））；
}
返回query.ToList（）；
} 

我重建它的想法是用3个新的数据源替换userRolesDataSource：CMSRolesDataSource、LMSRolesDataSource、AdminRolesDataSource。然后创建一个新方法，该方法采用username、systemadmin boolean以及类似于上述方法的可排除角色列表

我对编码还是相当陌生，我想知道是否有一种更简单的方法来完成所有这些。asp和c#的代码如下。提前谢谢
