I am thinking of following what buttons the user has pressed. I intend to choose the CreateUserWizard control that will create a database for me. The Membership class has got a few functions to identify who the user is..e.g. GetUserNameByEmail..
What i am trying to do, is to track what each user has pressed and use his input for sqlCommand.
For example, when the user presses the "post response" button, i want to record his identity and use it in sql to insert his message and identity..
The problem is that in the Users table that i made it has UserID as a primary key that identifies the user..and in the CreateUserWizard database or Membership cookie, it has its own functions fields.
So the question is how do i SELECT the users identity from the database/cookie created to me, and incorporate it into a statement in the SQL for my sqlStatement..
I need to obtain the identity of the user and use it in an SQL statement.. How can i achieve that?
You can grab the user_id from the Membership provider...
for example:
System.Web.Security.Membership.GetUser().ProviderUserKey
the will give you the user id of the current user - and you can use that value in your sql statement. If you're using the default Membership provider - this value will be a unique identifier (Guid) so:
Guid currentUserId = new Guid(System.Web.Security.Membership.GetUser().ProviderUserKey.ToString());

When regsitering in my site (ASP.Net MVC application), the users get inserted into the aspnet_users table. Since its a shopping site, I would want the users to have a customer id and all their details provided by them at registration in this Customer table as well. How do I link these 2 tables? Is it recommended to use the aspnet_user's UserId(Guid) in the application for other business processes.
Also, I would like to know when should a new record be inserted into the customers table.
I mean, when should a new customer be created. I guess its not good to create a record as ans when users are registered? Here, I want to know whats the norm? I felt it would be better to add it when a user adds an item to the shopping cart. Pls guide me.
Thanks in advance.
Add the UserId field into your customer table and then make a foreign key relationship back to the UserId in the aspnet_users table if you want to enforce relational integrity.
I'm not sure what you mean about when to insert the customer record. As long as you insert it after you have created the user (so that you have the user ID), you should be fine. It can happen in the same postback.
I'm not sure how you are saving the user. As in are you using one of the built-in ASP.Net controls or making the call manually?
If you are using the Membership provider as it sounds like you are, you can save the member using:
var user = Membership.CreateUser;
Guid userKey = user.ProviderUserKey;
//Populate your customer object.
//now use whatever EF/ADO/etc... to save your customer record.
I have a application which I would like to add custom fields to the users table. I am not sure how to work after adding the columns. The columns are foreign keys to another table which holds more details for the user.
I am using Linq-to-SQL. So every time I add a user (using the membership functions i.e. Membership.CreateUser(..)) I end up calling another service to update the foreign keys on the users table.
Any better way of doing this will be highly appreciated.
Why are you adding foreign keys to the User table, pointing to another table with additional info??
I would do it the other way around:
create your own table UserInfo
create a FK column in UserInfo that points to the row in your ASP.NET membership User table
leave the system-provided User table alone - so you won't run into problems when e.g. an upgrade to the ASP.NET membership system is rolled out.....
I strongly recommend you not to extend secure tables such like Users, Membership, Profile. Better create another one table in your database (not secure database) with full info which you need. Call it 'User' with foreign key to 'Id' of table User in secure database.
Question No 1
I am familiar with role management, a particular member in a particular role can do this and access this functionally. What I need to do is Manage individual user, not the role he is in.
For example, lets say I create a role, called "Sales". I setup the role permission what the sales persons can do. Now i want to keep a check on individual user. For example if this is "john", i want to show him the records only he created. If his is peter, I want to show him only that records which he created, not by john or other sales people.
Is there a thing called "User Management" in ASP.NET that we can use? If not we have to create it ourselves and I believe the integration with ASP.NET "Role Management" will not be that smooth.
Question No 2.
I am using control for user login. I want to create a session at this time so I can keep track of which user is signed in so I can show him the records only pertaining to him. How can I do that?
Your Q1 isn't really about Role vs User management (ie: authorizations) at this point. It's about audit tracking within your application.
And the way you do that is you capture the ID of the user who created the record in question with the record, so that later you can filter on that ID.
Pseudo database structure
Table Sales
Field...
Field...
Field...
CreatedByUser int not null, -- Populate this on creation and never change it again
ModifiedByUser int not null - populate this on every row update including insert
See ASP.NET Profile Properties.
Assuming the records in the database correspond to a unique ID for a user, you can store the unique id in a profile property per user.
1) If you want to filter records by the creating user, you need to record in your table the ID of the user who created the record. You can access the name of current user through User.Identity.Name and their ID (provider-dependent) through User.ProviderUserKey.
2) Sessions are created automatically in ASP.NET and provided you have a properly configured MembershipProvider, you can retrieve all the needed user info using the User object as shown above.
It sounds like you are a little unfamiliar with ASP.NET Membership and Roles capabilities, because they are actually set up quite well to accomplish what you are describing. I would recommend checking out this tutorial series:

You are talking about Authentication and Authorization. For question 1 you and implement a custom authorization provider to allow for user level control http://msdn.microsoft.com/en-us/library/aa479048.aspx For question 2, once you log in and are Authenticated, the session contains a userprinciple object that has the info in it automatically.
I added asp.net membership in my web application. Now I have one table where I have columns for user specific information UserProfile(FirstName, Lastname, DisplayName etc.). I didn't use Profile from membership because if in the future I decide to change asp.net membership for something else I want to keep user personal data in separate table. My question is: I use UserId (unique identifier from asp_membership_users table) as a foreign key in my custom table. Is UserId smart choice to connect these tables?
Yes, it's the primary key of the asp_membership_users table so it makes sense to use it as the foreign key of your custom table.
i am trying to show a list of users of my application "school", when admin logs in then he can view all the users in list but when school principals logins, he should get only users of his school, So i thought to get the current loggedIn userId first and then by that userId i'll get schoolId since userId is foreign key in school table...once i'll get the schoolId i can show the members of that school.
But my problem is how to get the UserID of currently loggedIn. I'm using MVC 1.0 Asp.Net -- "Membership"
if my logic above is wrong then please tell me the alternate good idea, so that principal can see only his users list..
Based on this question and answer by J. Pablo Fernández you can get the user id of the current user with the following code:
//It will only be a Guid if you are using SQL Server as the DB as oppose to MySQL
Guid userGuid = (Guid)Membership.GetUser().ProviderUserKey;
Here is the MSDN Documentation.
The Simple Solution
With the scenario you describe you would only be able to do this by retrieving the User information with the data stored in the HttpContext.Current.Identity. For example, if the HttpContext.Current.Identity.Name is the Username, then you would use that value to retrieve the User data for the principal that should include the UserId you can use to locate the appropriate school.
Alternate Solution
You might consider storing the SchoolId in the user's profile so that it is more easily accessible.
The easiest way that I've tried
You have to include Microsoft.AspNet.Identity
using Microsoft.AspNet.Identity;
Then use it like this
var userId = User.Identity.GetUserId().ToString();
