您可以在要删除的日期添加到期日期。然后你有一个定期过程（分钟;小时;天数......在购物车的情况下）假定用户已经注销（或过期），并删除现在陈旧的会话数据。 / BLOCKQUOTE>

I want delete the data from database when browser directly close.....

What I have tried:

i have a database name register.mdf its contain a table ONDETAIL i insert the username with using session and i also write the delete command in logout button click event...it is clearly working...but the problem is if you close the browser directly then it is not delete from database...please help....

解决方案

You add an "expiry date" to the date that you want deleted. Then you have a "periodic" process (minutes; hours; days ... in the case of a "shopping cart") that "assumes" the user has logged out (or expired), and deletes the now stale session data.
