Re: Load session variables when user automatically authenticates (Forms Authentication)

In that case, you will have code that logs them in, based on whatever. So, do it there.

It is done using a cookie. You set some user identification in a cookie when user selects "Remember me next time". When the page loads, read this cookie value and create session for that. I'd create a base page from which all my pages are inherited and do this in base pages OnInit event.

Cookies are kept in local machine, so make sure the information you keep in it is encrypted. So that no one can alter the cookie value and get access to some other account.

Thanks for the reply

I think that the base page is my best option

Thank you all

I need your help to write Add, Edit and Delete features. Here is the functionality details of the project:

1) SelectAll, ClearAll, Add, Edit and Delete is placed under FooterTemplate,
2) Textboxes for Name and Description is placed in FooterTemplate but its visible property is set to false, it has to be visible only if the Add button is clicked and SelectAll, ClearAll, Edit and Delete should become invisible
3) The edit and delete functionality should be enabled when any of the check box is selected and appropriate button is clicked

and the ASP Code is :

My requirement is not to use SQLDataSource rather Data through code.

The ideal output of the GridView looks like this : http://picasaweb.google.co.in/srihariacha/GirdView

This reads like you're asking us to write it for you. You can use any data source you like, but without persistence of some sort, what's the point of adding and editing data that will be lost ?

I user Sessions. Basically, when a user logs in , i carry the Username, to Display a message like Welcome "James" and each and every page i check if the Session is new, that means i chech if the Session variable is empty if its new, the user must be redirected to the login page. Now when the User logs off , i abandon the Session.

Hope it helps

Session variables are the best option to use it.Also you can use some database for logging the details of every user.

As the others have mentioned, use session variables. Do make sure when you are done with the user's session variable to delete it when finished. Otherwise, you will eventually (as this may take a very long time to have happen) run out of memory on the server where the values are kept.

The one step no-one else mentioned, is to create a new base page, which redirects to the login page if the user is not already logged in. From there, it just works.

Would you believe I inherited a project that didn't bother to do this ? If you went to a URL inside the site directly, it would just work, or blow up on the basis of missing sessions variables ( not the login, all sorts of other stuff was being stored in the session and never checked when it was accessed ).

Christian Graus30-Nov-08 14:57

That was just one example, that whole site was a nightmare. The other big thing that blew my mind was that all session variables were strings, and all strings were typed in everywhere. I actually found code like this:

if (Session["WeShouldDoStuffNow"] == "YES")

when doing some searching proved that it was only ever set to Yes, or No. I obviously centralised all the 'WeShouldDoStuffNow' values to a class, so that there were never typos, but I gave up, I defined YES and NO rather than move to bools.

Those can be a problem. Session variables are going to be a part of my discussion this up coming Tuesday evening in my VB.NET class I teach. I try to emphasize the importance of doing something like:

Dim MyUser As String = "UserName"
If Session[MyUser] blah blah blah blah Then
....

is easier and safer to work with than having the variable name inside quotations. It is a point I try to get across, and usually get mixed mileage every semester.

Christian Graus30-Nov-08 15:10

30-Nov-08 15:10

Yeah, I would create a class that contains all the strings, and use it throughout the site. It's hard to believe that anyone would fail to understand how important that is, once it's explained to them.

It happens from time to time, usually the student who is too busy IM'ing someone and not paying attention to the discussion. After they spend about two hours trying to debug the errors caused by the typos, it finally clicks.
