Question

when record is deleted in gridview when we press backspace button the record is back, when click that record the error message no records at rows 0 is found

Answer 1

This happens because when you delete the record, you reload the page and in essence create a new entry in the browser's history. The backspace key does the same thing as clicking the back button in the browser, and so you're getting what you asked for: the last page.

Answer 2

"Backspace" is the browsers back button. You're reading from the browser's cache.

When you click on the link, then that's a postback. And since the record has really been deleted on the server, you get the no records found error.
