Show links according to rights in MVC3 - asp.net

I m working on a MVC 3 application , it contain different links , i want to show the links according to the roles or rights. If Link A is to Admin thn Link A shouldnt be visble to Members right users.
How to achieve this thing in MVC ?
Thanks

#if (User.IsInRole("Administrator")) {
#Html.ActionLink("Administration", "", "Admin")
}

if you're not using the asp membership, you could do it this way, supposing you could get the role by using the username and that the role is included in the model:
#{
UserContext userDb = new UserContext();
var user = userDb.UserModels.FirstOrDefault(x => x.Username.Equals(User.Identity.Name));
if(user.Role == "Admin")
{
#ActionLink("Link's Name","SomeAction", "SomeController");
}
}
crude sample but if that what you're looking for.

ASP.NET Forms Authentication - getting user id

I see many similar questions, but not a single good answer. I'm using Forms Authentication and I would like to find AD account (domain/username) of the user that is currently logged in. I'm complete beginner in this field, and I would apriciate an example of how to do it. Thanks in advance.
I Used this to get my User Name of the user
username = (Session["UserName"].ToString()).Split('\\');
pUsername.InnerText = username[1];
try getting it from the session the one that is used for validation u can get that there
or u can do one thing is that get it from the database through SP on LoginClick store it in session and get it back where u need it.
I got it like this.
LP.UserName = UserName;
DataSet dsUserName = LBLL.validate_user(LP);
if (dsUserName.Tables[0].Rows.Count > 0)
{
Session["UserName"] = dsUserName.Tables[0].Rows[0]["userName"].ToString();
Session["entityUID"] = dsUserName.Tables[0].Rows[0]["entityUID"].ToString();
Response.Redirect("~/index.aspx", false);
}
else
{
lblMsg.Text = "Invalid Credentials. Please contact administrator!";
}
using System.Web.Security; // this will give you access to membership.
Inside your event:
// 2 examples:
bool loggedIn = User.Identity.IsAuthenticated;
string un = User.Identity.Name;

Restrict access to all asp.net pages

I am mainlining one asp.net Project, this project is configured in IIS. The website is open for everyone, when i review the code in asp.net page, its checking window login "enterprise id" and allowing all users to view the all the aspx pages.
Now, my management team requested us to restrict those who are under junior level employees.(Junior engg, Developer, software engg).
I have written the query, passing enterprise id and validate grade, if its junior level , returning "0" values,else returning "1" values.
My questions is, I do not want go and edit each page and check this query and restrict each page.
can you please suggest , how can i implement simplest and best way to restric the users.
Thanks,

Index.aspx
protected void Page_Load(object sender, EventArgs e)
{
string UserStatus = UtilFunctions.ValidateUser();
Response.Write(UserStatus);
if (UserStatus == "0")
{
Response.Write("<div><font color=red><h1>You are not authorized to view this page</h1></font></div>");
Response.End();
}
}
Utilifunctions.cs
public static String ValidateUser()
{
string CurrentUser = getLoggedOnUser();
using (System.Data.SqlClient.SqlConnection myConnection = new SqlConnection(ConfigurationManager.ConnectionStrings["TestDB"].ConnectionString))
{
using (SqlCommand myCommand = myConnection.CreateCommand())
{
myConnection.Open();//Opens the Connection
myCommand.CommandText = "Select Permission From Temp_Validate Where EnterpriseId='" + CurrentUser + "'";
SqlDataReader IDReader = myCommand.ExecuteReader(); //Gets the ID
IDReader.Read();
string UserStatus = IDReader["Permission"].ToString();
IDReader.Close();
return UserStatus;
}
}
I implemented the above functionalite in my index.aspx page, if the userstatus equal to "0" , it will display the "You are not authrized to view this message" and it will end.
I have around 30 aspx page,its currently running in Production. I do not want go include the same code (index.aspx) in every page load to stop the user validation.
could you please suggest how can i implement without editing all pages.

You have a few options, here:
1) Set up role-based access with Owin or AspNet.Identity. This is probably your best option, but I couldn't find a good tutorial for you. Those packages are well-documented, however, and I'm sure you can figure them out with some effort.
2) Build a Roles table, and customize access yourself. The best example I found was here: http://www.codeproject.com/Articles/875547/Custom-Roles-Based-Access-Control-RBAC-in-ASP-NET
3) Redirect unauthorized users without the use of roles. So something like:
public ActionResult SecurePage(User u)
{
if(u.level == "junior"){
return RedirectToAction("CustomErrorPage");
} else {
return View();
}
}
I'm not sure that that option is terribly secure, but it should work.
Hope that helps!
after setting up roles you can use a web.config file in every directory specifying authorization and/or use the 'location' element in the web.config file.
First off, sorry about the confusing code. I've been using MVC, and you've clearly posted your code behind.
I don't think that you can achieve what you are trying to do, without adding your code to each page, or learning about roles. You could reduce some code duplication in a number of clever ways, but I can't think of anything that doesn't seem like a total hack.
If you want to, say, put all of your secure pages in the same directory, and restrict low-level access to that directory, you are going to have to filter by specific users or, if you can implement them, roles. As I understand it, the deny and allow nodes in your web.config file are setting server side (so IIS, probably) authorization rules, so the keywords and rules you can use are limited. Check this page out, for some basics:
http://weblogs.asp.net/gurusarkar/setting-authorization-rules-for-a-particular-page-or-folder-in-web-config
While it is likely POSSIBLE to build a rule based on values in your DB, doing so would probably be far more work than it would be worth.
Sorry that I can't offer a more satisfactory answer, but I would recommend: 1) Get to work, and add a check to the code behind for each page, or 2) (and I highly suggest this option) close this question, and post another, about implementing roles in .net, and assigning roles to users, in code. If, say, you can use your login page to assign every junior-level user the custom role of Junior, and place all of your secure pages in a directory named SecurePages you could add the following code to your web.config, and achieve exactly what you are trying to do:
<location path="SecurePages">
<system.web>
<authorization>
<deny roles="Junior">
<deny users="*">
</authorization></system.web></location>
Good luck!

How to get all user list from orchard

I need to get all of users with their Ids whose are created by orchard admin panel. Now I need all list and I will use it in another service.
Or, I want to get Orchard user table "[Orchard_Users_UserPartRecord]" from entity framework like this code
public IList<UserAttendance> ShowAllUserAttendance()`enter code here`
{
using (UserAttendanceDbContext _db = new UserAttendanceDbContext())
{
return _db.UserAttendances.ToList();
}
}
How can I do it?
Thanks,
kibria
See following.
var userProfiles = _contentManager.Query<UserPart, UserPartRecord>() .List() .Select(user => ((dynamic) user).ProfilePart) .Select(user => new {user.FirstName, user.LastName});

storing logger information asp.net

i am building site where there are three types of user. Admin,Merchant and Assitant User.
Where to store information so that my application will know which user has logged on( whether it is admin or assitant user or merchant)
Thank you
You want to look at ASP.NET Membership and Roles.
string path = DateTime.Today.ToString("dd-mm-yy") + ".txt";
if (!File.Exists(System.Web.HttpContext.Current.Server.MapPath(path)))
{
File.Create(System.Web.HttpContext.Current.Server.MapPath(path)).Close();
}
using (StreamWriter w = File.AppendText(System.Web.HttpContext.Current.Server.MapPath(path)))
{
w.WriteLine("\r\nLog Entry : ");
w.WriteLine("Membership.GetUser().UserName);
w.Flush();
w.Close();
}

ASP.NET username change

I have an asp.net site which uses the ASP.net Membership provider. Each comment, entry etc in the DB is tracked by the userID.
Since MS doesn't provide a way to change the username, I've found the userNAME in the "users" table in the DB and there is only 1 place where the username appears.
My question is,
Is it safe to provide an "edit profile" page where the user is allowed to edit their own username. Of course i would handle this change in the background by directly changing the "username" value in the DB.
Are there any downsides to this ? I've created and modified some test accounts and it seems to be fine, i am just wondering if there is any known negatives to this before putting it into production.
cptScarlet's link was good, however I despise using stored procedures if I don't have to and I favor Entity Framework whenever possible. Here's what I did to change the user name, using EF 4.0 and .NET 4.0:
Right click project -> Add New Item -> ADO.NET Entity Data Model
Give it a proper name, I chose "MembershipModel.edmx" and click Add
Select Generate from database and click Next
Add the connection to your 'aspnetdb' database (the ASP.NET membership database)
Give it a proper name, I chose "MembershipEntities"
Click Next
Drill into Tables and select aspnet_Users
Change the Model Namespace to MembershipModel
Click Finish
Now you can add code to create the EF object context and modify the database:
public void ChangeUserName(string currentUserName, string newUserName)
{
using (var context = new MembershipEntities())
{
// Get the membership record from the database
var currentUserNameLowered = currentUserName.ToLower();
var membershipUser = context.aspnet_Users
.Where(u => u.LoweredUserName == currentUserNameLowered)
.FirstOrDefault();
if (membershipUser != null)
{
// Ensure that the new user name is not already being used
string newUserNameLowered = newUserName.ToLower();
if (!context.aspnet_Users.Any(u => u.LoweredUserName == newUserNameLowered))
{
membershipUser.UserName = newUserName;
membershipUser.LoweredUserName = newUserNameLowered;
context.SaveChanges();
}
}
}
}
Note: I did not account for application ID's in my code. I typically only ever have one application using the ASP.NET membership database, so if you have multiple apps, you'll need to account for that.
