You can only tell your other user that something was deleted after the fact, or you can lock records that are open and forbid deletion ( what most people do ).

hi Graus,
My end target is not just display user name, but i want to display it to users which are viewing same data,
Means take an example, that there is student records 1,2,3,4.
there are users
A,B,C
Now A is viewing student recored 1.
B is viewing student record 2.
Now if C is going to delete student record 1, then A will get message that "student record 1 is deleted by A"
all the data are come from database means A,B,C and 1,2,3,4.
And please send me if you have solution.
Thanks

U can put a log there in DB with user ID of the person deleting record.
When any one tries to fetch deleted data refer log table first and if it has entry for the same; pick user name from there and if no record exists for tht student(ur example)in log, pick actual data and display it.
Hope it will give u a solution
With Thanks & Regards

I want to save database round trip because there are 20 pages, and each page load if I will go to check whether this particular record is deleted by another user.
I think it is not an fesiable way.

Hi,
I know, but in my application, I have to allow both user to view and same data, but if any of one is deleting the data then I have to give message that this data is deleted by this particular user.
And redirect another user to home page.
So I have to access, another session user, from current user session.
Means if current user is going to delete data, at the same time he can access the another user, who is seeing same data, and he will give message that data is going to be deleted.
Thanks

Hi,
First point is this how you are going to notify the user who is already watching the deal(until he refreshes the page).
So its better lock it while it is viewed by other and for this create a log in ur db in synchronisation with ur Session variable..

As you told me it is not a big deal then just keep log in ur db of current user and the record id viewed by them and update it evrytime they view some another record. When a user try to delete the record it is first checked in the logtable it is being viewed by someone or not. If it is viewed by some one then just return the person name or id as hyperlink.
But u hav to make some messaging system in your application to notify the another user about the delete.

sorry, by mistake i gave you 1 in rating.
I want to give message to another user that particular recored is deleted and recirect him/her to Home page, when a User is going to delete a record.
So I have to access session(instance) of another user, but I havn't idea, how to access another user at the same time who is viewing same record.
Thanks

ok it is a pretty difficult task.
there is a solution but may its not the be the best one but it will work for u.
we reached to the solution that u will get the username of the person viewing the record.
then just in some table update a flag for notification with the useraname of viewer.
Now add a component in your application that will be called on each page . On that component place a alert message which wil be fired when the flag of the notification table is true. And through ajax get the dataset refreshed after few seconds say 3 sec.
Hope now u get the solution...

I got an idea but it will slow down ur page litlle bit..
use ajax and refresh the dataset after some time say 3 seconds and if it dont find any data there then just display a alert message the record has been deleted..
So it suits ur requirement??

Hey thanks for quick reply,
but don't we have anything through which we can notify another session of user, through Global.asax Application_start events.
I am planning to use Application_start event by defining arraylist.
we user is going to view record, data is inserted in this arraylost.
then when user is going to delete the page it will check for same data from Application array list.
And through it he can find session of that particular user and give message.
but i don't know how to give message to another user with out he is not firing any postback event

if u are using some login system in your application then it is very easy to track users otherwise there are some commands in c# to get ip address of the user(but it is not much suitable for u.)

Hi,
Thanks for your answer. What I really wanna do is to put the list box item to the textbox (which already have text there). I am testing with alternative way now. I try to put list box item to text box when i click on a button. But I still cannot put the item between other text. If you have some more idea, pls drop me a line.

You can do drag and drop, but it's lots of javascript. There are examples on the web.

Yeah, I have some examples of javascript for drag and drop. But I want to use javascript if there's no other options coz I am very new to that.
