When working with ASP.NET, always look at the HTML source when something doesn't work. Even better, install Firefox and firebug, and debug your javascript in realtime. If these are server controls ( and if they are not, this belongs in the web dev forum ), if you look at your source, your service control called lstShowHistory is almost certainly not called that on the client. So, you need to inject javascript that creates variables that contain the client side Id's of these controls, then this sort of code will work.
