first of all you should have a table in database database that contains (user_id, company_id,  password, auth_level). the auth_level can be used to grant specific content/page access to each user of each company. but, you need to override the authentication process as bellow.


protected void Login1_Authenticate(object sender, AuthenticateEventArgs e)
Login login = (Login)sender;
if (AuthenticateLogin(login.UserName, login.Password, Session, Request))
e.Authenticated = true;
e.Authenticated = false;

private bool AuthenticateLogin(string userName, string password, HttpSessionState session, HttpRequest request)
//DBConnection is my own implementation of DataBase connection.
//That simply connects and executes queries.

DBConnection dbc = new DBConnection();
string qry = "SELECT * " +
"FROM Users, SecurityLevels " +
"WHERE (UserName = '" + userName + "') AND (Password = '" + password + "')";

SqlDataReader reader = dbc.GetDataReader(qry);

bool retVal = reader.Read();

if (retVal)
UserData user = new UserData();
user.UserID = (int)reader["userid"];
user.SecLevel = (int)reader["SecLevelID"];
session["user"] = user;

reader = null;

return retVal;

The UserData class contains simple getter/setter for the attributes i listed above for the table (except the password ofcourse). you can also add anything more in this class if you want.
Then whenever you need to check access permission for a user, try this:


//assume SecLevel is maximum when it is 0.
//the higher SecLevel of user, the lower privilege he has.

int desiredSecLevelForPage = 2;

//not logged in. redirect to login page.

UserData user = (UserData)Session["user"];

//check if current user has proper access
if(user.SecLevel > desiredSecLevelForPage){

//.... rest of the code for the page...

hope this makes sense.

Would it not be simpler to use the built-in login control, and web.config user allow/diallow rules to achieve this?

I know that this would mean you would have to add your users into the "standard" user database, but I'm sure it's not complete rocket science to point the login control to your own database (although I haven't looked at this!).

(How) Can i use the form elements of a user control from another user control???
Hi, i have a user control with 4 other user controls. Actually i have 4 panels and each user control is inside a panel. Its like a 4 page form which are all connected to each other. Is it possible to have access to web controls that i have in my user controls from the main user control. In my main user control i have a submit button and a tab list. User can browse through the tabs and each tab is bound to a panel. so clicking on tab1 makes panel1 visible which holds the first user control, second tab makes second panel visible and the rest invisible and the second panel holds the ...

How can a user-control know the name of the web form that uses it?
How can a user-control know the name of the web form that uses it? How can I code in the user-control access to controls of one of the web form that may use it? You reference the Parent property of the web user control in the user control code. For example, if you want to get a Button found on the web form that contains the current user control, you would put the following code in the code-behind of the user control (in C#): Button myButton = (Button)this.Parent.FindControl("myOtherControlButton"); The FindControl() method accepts the ID of the control you're ...

I can create new user (auto-logged-in) but I can't log in using login-control???
Hi there,  I am a little at loss here. I can create new user and I can set in code that I should be logged in after creation - but if I logout, I can never log in again. I've tried creating new users to be sure I didn't make a mistake with the password, but I simply can't log in! The user is created in database and the page visit is logged in my log table (so I can update the database) I've tried Dim r As Boolean = FormsAuthentication.Authenticate("ajuaju", "xxxxxxx.") which returns false even for the correct password. Is the authentication p...

user control data entry form, use same codebehind as web form?
Hi All, I have a quesiton about the approach I'm taking. I have a series of report forms which I have been in the process of consolidating to a single, generic page and subs/functions in a single code-behind. All the reports can use the same set of data entry elements (a dropdown, a radio list, and a textbox). I'm trying to convert these elements to a user control. However, this user control seems to need to inherit differently than the rest of the code-behind. I've been using a single class in the code behind. Is it feasible to separate out the data entry? the code behind im...

I have a web user control being used by another web user control, but the one being used will not display the labels in the resx file.
I am using DotNetNuke version 3.13 (might be 3.013) on a Window's XP machine, SP2. I have what I find to be an extremely odd situation. I have a project called TDS.Controls. This project is a web control library. Each control has its own resx file, which is located in the App_LocalResources directory. Each control inherits from Framework.UserControlBase, just like DotNetNuke's User control in DNN\Controls\User.ascx.vb. As a matter of fact, this control is doing the exact same thing I am trying to do. It is a web user control with its own resx file being used by another web user control (See ...

UpdatePanel within a web user control resets data of controls outside the user control
Hello, I have a usercontrol on my page which displays a running marquee text. It makes use of an UpdatePanel (within the user control) to refresh the marquee text (within the updatepanel) at periodic intervals. For this I added a timer control and its tick event as an async postback trigger for the UpdatePanel. I have a lot of textboxes and dropdown list boxes (all with runat=server) on the page outside the above user control. These are also contained in different UpdatePanels. Problem is, when the user control does a postback to refresh the marquee text, it causes some of...
