Answer Posted / meganadha reddy k.

I guess what you mean is AutoPostBack="true" in which the
index change of a drop down box will be posted back to
server.
Please correct me if I am wrong.

To know the difference between autoEventWireup="true" and
autoEventWireup="false" please refer the below link:
