Show data from another table when logged on ASP .NET - asp.net

I'm using ASP .NET with Oracle XE as my database and I use the ASP .NET Membership tools with Oracle as my provider. The ASP .NET Membership tool creates its own set of tables on my database.
My question is how can I show the data from the MemberInformation table when the user is logged on?

you can use Membership and MembershipUser' in theSystem.Web.Security`
MembershipUser user = Membership.GetUser();
string userEmail= user.Email;
Now using the user object you can access most information of the currently logged in user. These classes are powerful you can even use them to update user data.
See these Links for details:
MembershipUser

acessing username in web api controller when database table stores user as integer

Inside some web api controllers, I would like to access the User as indicated in this answer: https://stackoverflow.com/a/12705062/538962
sample code from answer...
[Authorize]
public List<Product> GetProductsFromId()
{
string username = User.Identity.Name;
return _productService.GetProductsFromUsername(username);
}
The asp_net membership tables in my scenario are on a different database server than then the database server the application runs on. The database for the application has its own Users table with an IDENTITY column as the Primary Key on the Users table, and then other tables that include a CreatedByUserID and UpdatedByUserID columns are integers based off the IDENTITY column in the users table.
The issue is that if CRUD type operations depend on the user being updated in tables as an INTEGER, just accessing the username alone is not sufficient; we still have to get to that username's corresponding UserID.
This could be done with another join to the Users table, but this seems a bit kludgy. What would be the best way to go about handling this issue?
From the perspective of ASP.NET Web API, using membership provider and the out-of-box FormsAuthentication is already kludgy, so why not the join? :) Anyways, assuming your web API is consumed by only the web clients and FA is cool, you can use the UserData of the FA ticket to put in the user ID. That way, you don't need to get the ID by hitting your DB every time. But you will need to create the ticket yourself and not let the default out-of-box implementation do that for you. Then, in the PostAuthenticateRequest event, you can read the user ID from the ticket and set it in the identity. Of course, you need to create your own custom identity for this with an ID property or if you are on .NET 4.5, you can use FormsIdentity itself but you can use the NameIdentifier claim to store the ID, perhaps. Check this out - ASP.NET MVC - Set custom IIdentity or IPrincipal.

Avoid Multiple calls to GetUser when using ASP.NET Membership

I am using ASP.NET Membership in an ASP.NET MVC 3 Web application project.
I have installed the ASP.NET Membership tables using Aspnet_regsql.exe and now my main userTable has a foriegn key called "userID" which points to the "UserId" of aspnet_Users.
This "userTable" is connected to many tables. So for every operation now I require the "UserId" from aspnet_User using the username with which the user has logged in.
For this I use
MembershipUser user = Membership.Provider.GetUser(username, true);
now for each and every operation I have to make this call and get user.ProviderUserKey to continue with my other operations.
I am thinking there has to be a better way to do this. Is any any built in way to do this ?
The ASP.NET Membership Provider isn't intended to provide the ProviderUserKey... perhaps you could use the username instead? You can always easily access that through Context.User.Identity.Name.
I always use:
Guid userId = (Guid)Membership.GetUser().ProviderUserKey;
You get the user information once and put it in forms authentication cookie with user data encrypted.
For subsequent calls you use Context.Identity for the user information
You can keep the relevant information around in the cache, for example in a Dictionary<string, Guid> where the key is the user name (which you can lookup using HttpContext.Current.User.Identity.Name or Thread.CurrentPrincipal.Identity.Name), and the ProviderUserKey is the value.
Build this dictionary either on-demand or initialize it once, and put it in the ASP.NET Cache, Session or Application (of course watch our for serialization and concurrency issues).

add user and assign role in aspnet membership through sql servers SP

Tech - asp.net 3.5, Sql server 2005
I have integrate aspnet membership for my webapplication.
I am adding some users (member) from importing excel file.
So how can I add that user and role of that user in aspnet membership tables?
NOTE - I have SP which is used to add member in DB from uploaded excel file, I have wrote insert trriger on membertable.
Do not insert DB records manually. Use .NET's Membership Provider's stored procedures to do that, for example aspnet_Membership_CreateUser and aspnet_Roles_CreateRole.
But better off, use .NET's classes/methods to do that. They encapsulate the whole mechanism for you:
Membership Provider
Role Provider
First you create a user, then you (optionally) attach role(s) to.
UPDATE December 2015
Folks keep reading this. It's important to know that for a few years now, there is a totally different paradigm, ASP.NET Identity. please use it instead of the old Membership Provider.
Abhi you should use
//to create a user
MembershipUser newUser = Membership.CreateUser(UserName, Password, Email);
//to attach created user some role
Roles.AddUserToRole(newUser.UserName, role);
Update
For that you can for for membership stored procedure aspnet_Membership_CreateUser to create a user or you can create one for you to insert data into user and userinroles table.
I would encourage you to refer link
You can simply do INSERT in the AspNetUsers table with empty PasswordHash and SecurityStamp. Then we have a "forgot password" flow that establishes credentials using ASP.NET Membership.

Active Directory Authentication & Custom Roles

I havent worked on ActiveDirectory Membership provider earlier, I have a doubt on creating an application using AD membership provider. If I need to foreign reference a user in a different table(lets say a custom role table ) then what primary identifier(Foreign key) should I use to identify the user in the the table which holds the relation of Role and the users.
Also , where is the additional information(other than AD details) about the user is stored like User Name, Department, Current project etc.
Is a snapshot of Active directory taken frequently and stored in a table in the database which is then used in sql joins?
The base membership provider (and derived providers such as the ActiveDirectoryMembershipProvider) uses UserName as a functional key (queries for members expect UserName as the key query parameter and return a single MembershipUser object). Those queries return MemberShipUser objects that have basic membership information—including roles, email, comments, etc. If you want to combine the ADMembership Provider with extra information, you're best off using the UserName as the key to do so. Storing extra data is easier if you use a database because .UpdateUser only commits Email, Comment, and IsApproved properties.
And no, snapshots are not taken, though you can enable caching if you wish. The provider queries AD directly when it needs the information.
The aspnet membership database when created resides in App_Data folder and is quite handy as it supports all the Login controls very well. The user roles can be very well managed by the aspnet configuration manager. The profile properties are managed all by the the database itself.
The database thus created can be seen in the server connections. If you analyze the datatbase you will see that every user has a specific userId apart from the username. Both of them are unique. You need not copy all user data in other tables. You can specify the related data using joins. Once a user is logged in, you can refer him/her by User.Identity.Name (c#) in your code behind.
Kindly view the database tables using the Server Explorer in Visual Studio and you can view the tables structures -- aspnet_Users, aspnet_Membership, aspnet_Profile etc...

How to connect Calendar control with existing Membership system in ASP.NET?

I have a built-in Membership system in ASP.NET and I handle member data with Profiles in web.config.
I would like to add an Event Calendar where a member could add notes to any day he wants but I don't know how to integrate the Calendar control with the existing Membership system.
I can't query a database because I don't handle member login credentials manually, Login control does that for me so I would have to connect the Calendar with the existing ASPNETDB.MDF Membership database but I'm clueless.
If you are using built-in sql membership provider then it is easier. You can get Logged-in user and access database using that.
object id= Membership.GetUser(Page.User.Identity.Name).ProviderUserKey;
Now yo can store calendar data in table and link user with his calendar with his id (which is GUID).
EDIT:- Here are some links for exploring membership further.
