Question { Syntax Softtech, 6651 }

What does the "EnableViewState" property do? Why would I
want it on or off?

Answer

Enable ViewState turns on the automatic state management
feature that enables server controls to re-populate their
values on a round trip without requiring you to write any
code.

This feature is not free however, since the state of a
control is passed to and from the server in a hidden form
field.

You should be aware of when ViewState is helping you and
when it is not. For example, if you are binding a control
to data on every round trip, then you do not need the
control to maintain it's view state.

ViewState is enabled for all server controls by default. To
disable it, set the EnableViewState property of the control
to false.

An inprocess is one which runs in the same process area as
that of the client giving tha advantage of speed but the
disadvantage of stability becoz if it crashes it takes the
client application also with it.

Outprocess is one which works outside the clients memory
thus giving stability to the client, but we have to
compromise a bit on speed.
