I have a question, when I compiled my asp.net c# web application and transfer the ".dll" file to my hosting server which is godaddy. What happened was, all my users that used to show "online" all appears offline at once. I query db to get that online status of a column called "LastActivity" I guess, when that happens, I would like to sign out everyone so that they can relogin? How can I do that? I'm using form authentication.

Also by default it does not display anything, so after the .aspx extension I add .aspx?UserId=1 and it displays the first record on the database. But if I change it to .aspx?UserId=2 or
.aspx?UserId=3 etc, it still displays the first record on the database. Why does it not display the next user name. (I am logged in with admin and it is displaying a user that is in another role group)
Using formview or details view, I want to allow users to both input data into columns (I know how to do that) and add additional columns to the existing table if necessary.
View 3 RepliesI'm populating a gridview showing all the personal log entries for all users which have entered information into the database.
There's the following columns in the database table:LogID, DisasterID, UserName, DateEntered, and LogEntry.
I can get the gridview to populate with this information just fine depending on the DisasterID.
Right now, it shows the username next to each and every one of their entries.
How would I configure it so that it would list the username once and all their entries, followed by another user and all their entries, etc?
different return for added users and for rejected users?

How would I go about changing gridview colours and detailsview colours depending on who logs onto my website? Is there a way of doing it in the code behind (basic example follows) :-

Gridview/Detailsview Headerstyle =
Gridview/Detailsview Controlstyle =
End If
The gridview and detailsview are connected to SqlDataSource controls and are databound to a SQL server database.

Lets take an example of online ticket booking system. Many users could be booking the tickets at any point of time. a GridView displays the list of Allotted and Free seats If a seat gets booked, this information must get updated in all the opened pages in user's browser. User need not require to refresh the page to see if a seat is booked or not Should i put GridView in update panel and keep looking into the databse constantly ??? This could turn out to be a heavy work if databse is too large any other alternative?? or should i stick with the above approach....?

View 12 RepliesIn my application, the client must sign (using a certificate) and send data to the server.My doubt is how should I do it?
To sign on the client side, I should use ActiveX right? My problem is that firefox doesn't support it.
Signing on the server side I have two options:
Save the private key on the server and use it when necessary (if the data is modified during the transaction it will sign false data)Send the private key when necessary (may comprise the key)
Despite using SSL, I'm not very confortable with any of the two options for signing on the server side...
