Postback Versus Non-Postback Events
Postback
events
cause the form to be posted back to
the server immediately. These include click-type events, such as
Button.Click. In contrast, many events, typically change events, are
considered non-postback because the event is not
posted back to the server immediately. Instead, these events are
cached by the control until the next time a post occurs. Controls
with non-postback events can be forced to behave in a postback manner
by setting their AutoPostBack property to true.
Table 3-3 summarizes the controls with postback and non-postback events.
