Hi,

I have a search button, on clicking it shows 10 results first and on scroll show another 10 and so on. Scroll is handled by page index using stored procedure. On each scroll page index will be page index + 1.

If I scroll 2 times there will show 20 data and on clicking search button for new search page index will be changed to 1 but scroll cannot be changed, it shows 20 data but I need 10 values to be shown first.

I have done so far is using $(".MydivName").empty(); to clear previous data in the div. But the scroll cannot be cleared.
