"while leaving the page" means closing the browser ??

This is impossible. The session lives on your server. You would have to pass down to the PAGE a behaviour when someone leaves the page, and it won't always run( for example, if someone closes the browser). You can, of course, emit javascript to your page on the basis of a session value.

sir thanks for your reply......sir i had one more doubt, can i fire pop up in page_unload event in .cs

Why do I get a 1 vote ( this is bad ) for giving a correct answer ?

You need to read about how the web works. All C# code runs on your server. No, you cannot fire a popup. You can't stop your whole page lifecycle from running for every page request. All you can do is emit the javascript to show a popup once the page life cycle has ended and the browser is showing the page.

I don't usually ask for votes, but if you voted me 1, please change it to a 5 if I helped, or explain why you gave me a bad vote. Marking my reply as the answer also helps me AND helps the site because it shows the question was answered.

Sir actually i got one code while searching abut this issue.........

window.onbeforeunload = confirmExit;
function confirmExit()
{
return "your changes will be lost if not saved. Are you sure you want to exit this page?";
}

while applying this code i am unable to leave the current page.....my task is completed half.......
now the half task should be completed is
1.)two button click events the above code should not work and second condition
2.)using the session value it should work
3.) when i am applying this it is showing two options "stay on this page" and "leave this page" instead of this two options i need only one "Stay on this page"

by above points my code should be like this(assumption)
if(button1_click!=click or Button2_click!=click)
{
if(session["user"]=="A")
{
alert
}
else
{
No alert
}
]

sorry for above example but i am unable to explain properly. but like that i my logic should be is it possible

Yes, you're right, that code is broken. You need to return the result of a prompt.

A confirm box is what you need.

Still curious why you want my help, if you won't vote for my answer, and perhaps even down voted me.

When i am using this below code i am getting two options "stay on this page" and "leave this page" but i want only stay on this page is it possible...........

window.onbeforeunload = confirmExit;
function confirmExit()
{
return "alert message for testing";
}

Christian Graus 23-Jan-14 16:35pm

OK, I didn't know it worked that way. In that case, no. How would that work ? If your only option is 'stay on this page' then there's no option at all. Instead, I think you want to show a message saying you won't let them leave, and return false, that MAY work.

But when i am clicking on the ok button of a popup it is redirecting the other page........i want to stop that.......is it possible
