You are doing it wrong. You already use window.open. This call returns window object which you discard. But you can use it:

JavaScript

var someWindow = window.open(/* ... */);

// ...

someWindow.close();

how it declared in cod behind pls suggest ...?

It has nothing to do with code behind... Code behind does not remove pages, it only responds to HTTP requests and generates HTTP response. In a response, you can generate some text of a script, but manipulation with the pages can be done only by the script, on the client side.

You are right. Moreover, it has nothing to do with code behind, no matter PHP or ASP.NET. :-)

Solution 1

Do it in Javascript as part of the page script:

JavaScript

setTimeout("window.close()",40000);

should do it

Solution 3

You need to use:

string jScript = "<script>indow.open('', '_self', ''); window.close();</script>"

You might want to look at the dates on questions before answering them.

I seriously doubt the OP is still working on this 5 years later, and other answers have already covered the topic.
