be encrypted for more security via 1) web.config file's
<Configuration>
<system.web>
<pages viewStateEncryptionMode="Always"/>
</system.web>
</configuration>
or 2) page directive:-
<%@ Page Language="C#" AutoEventWireup="true"
CodeFile="Default.aspx.cs" Inherits="_Default"
ViewStateEncryptionMode="Always"%>

can set to off:
1) at entire page level or at specific control level
2) at machine or application level in web.config file
