updating the gridview with the button on the same gridview
<p>I want to develop a book store Application in Asp.Net. For that one of my page contains  a text box and search button, if you write some book name and search for it , it will show result(title,author,no.of copies,button"add to cart") in gridview , i have button on each row as Add to cart. if we click on it ,it will open a new gridview with selected book details ( title,author,copies purchased )at the same time i want to decrement the no.of copies in first gridview. if i click the same button again i want to increment the copies purchased and again to decrement  the no.of copies. till now am not saving anything to DB.the thing is if i click on search button now i want the details with affected "no.of copies" in first gridview. </p>

<p>I think you guys understood my Question. </p>
