This is a bizarre requirement for a web app. Your problem is, you cannot know if the first person has left the page. The best way to handle this is to store what pages are 'in use' in the database, because you also need to store the time/date they became in use, and impliment a timeout so that the user loses the page after a while. Otherwise, I can browse to your site ( and I assume I'd be one of only 2-3 people worldwide doing so, for your requirement to not make the site useless ), turn off my PC and your site is broken.

I would like to add a few things that might work for you...
I think that Session State is based on the user, right?
- As Christ said, you should store the pageid and status "in use" in the database.
- If you move to other page then change the pageid.
- Check whether a particular page is in-use or not in every page_load.
- Use "Session" in your page. (you wanna say that you have nothing to store in the Session variable? anyway, use it.. otherwise, you won't get "Session_End".. )
- Delete the record ("pageid" and "in use") in Session_End event.
- Don't forget to set "Inproc" in web.config..
I think that it might work.. but it is better if you can change your requirement..

hello friends,
I am using paypal controls in my project and i am having two problems which i don't think it is solvable by coding.
the first problem is:
when after clicking on "Buy Now" button of paypal my IE blocks the cookies of the paypal site.when i unblock the site cookies it works fine but for this i am using the Internet option->privacy->unblock the sites.....
but what i want is that any way to solve this problem in asp.net..................
The second problem is:
when paypal site open, it open in a child frame.After completing the transaction process, when i click another link of my parent frame then it shows in the new frame which is not allowed so what i think is to open the paypal site in new window.
so is there any property of "Buy Now" button which open paypal into the new window........
if you have any way to solve this problem, then please reply me. on mail or on forums....
help will be highly appreciable.......
thanks in advance....

If the subjects are coming from a table, the most likely way to render this is with a repeater.

True. It is because now you have overcome and have avoided a costly server roundtrip and doing it on the clientside itself.

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)

if (e.Row.RowType == DataControlRowType.DataRow)
{
quantityTotal += ((int)(Eval("Quantity")));
priceTotal += ((decimal)(Eval("SubTotal")));
}
}
there is a compilation mistake.
i think i should use the <%# (inline binding) along with this Eval("Quantity") at opening and closing
how to do this

|
|
use like this
<%# Eval("Quantity") %>

i was trying to know the basic differences between
eval("abc")
databinder.eval(container.dataitem,"abc")
as in the item template and edit item template the formmer one is working .
i am not being able to understand in which condition , i should use which one, the former one , just making the syntax easy , i think.
