whats the purpose of AUTOPOSTBACK property for the controls in asp.net?..

In classic ASP, postback could be triggered by clicking a
button. ASP.NET provides property to the web controls to
trigger a postback on certain events like checkbox/radio
button .. checked/unchecked etc. This gives a lot of
flexibility to the developer to handle the event on server
side.

Answer / waqas ahmed (http://www.themav

It allows you to control and change dependent fields in the
web form.

for example: if i have a dropdown of states and another
dropdown of cities with reference to the state, i want to
change the cities listitems when the user changes the state,
i would use autopostback property (good alternate is ajax
dropdown extender) and it will refresh my page by using
onselectedindex_changed property with my desired cities list
which is on the basis of the state selected.
