You can use return statement in javascript and return false if you dont want postback.

Might be the reasone behind it is you are populating the listbox on every postback just check Ispostback property when page is first time loaded populate listbox else no need to populate listbox again, if viewstate is enabled.

Check viewstate of your page <%@ Page Language="C#" EnableViewState="true" should be true
