i have filled a listbox and i put some code to be executed when selection change using event SelectedIndexChanged, but nothing happen
i know that changing the property AutoPostBack to true could solve the problem put if not what is the benefit of the event

is it to use client scripting (while temperory disable for Server side scripting)

Using AutoPostBack won't solve the problem of an event not firing if something is wrong. It simply means that changing the value of a listbox will cause a postback. Any other client-side event that causes a postback will post the page and the listbox's SelectedIndexChanged event will fire (along with any other event(s) on the page that are triggered by user inputs.

Are you confusing server side event's with client-side events? With ASPX any "event" you write a handler for is a server-side event. Web forms work on the postback model. If you want to do things client-side only, you'll have to work around the postback model and write javascript to handle the control's client-side events.

What is not happening that you are expecting to have happen when you change the listbox selection?
