ViewState is the mechanism ASP.NET uses to keep track of
server control state values that don’t otherwise post back
as part of the HTTP form. ViewState Maintains the UI State
of a Page
ViewState is base64-encoded. It is not encrypted but it can
be encrypted by setting EnableViewStatMAC=”true” & setting
the machineKey validation type to 3DES. If you want to NOT
maintain the ViewState, include the directive < %@ Page
EnableViewState="false" % > at the top of an .aspx page or
add the attribute EnableViewState=”false” to any control.

view state is nothing but store all the current page
informations and the control details when the page is
postback.all the control details and values to be stored in
hidden field.Those hidden fields are creating dynamically
depending upon the page placed controls.If you want to
fetch the values of the previous page control(ex:'Name' is
the previous page control Id)

Get the value of name from second page

sample code:

string get_Name=viewstate["Name"].Tostring();

Answer / suhasini suresh

The load view state stage only happens when the page has
been posted back. During this stage, the view state data
that had been saved from the previous page visit is loaded
and recursively populated into the control hierarchy of the
Page. It is during this stage that the view state is
validated. The view state can become invalid due to a
number of reasons, such as view state tampering, and
injecting dynamic controls into the middle of the control
hierarchy.

Answer / aravind

*Viewstate object is used to persist data of variables
across postbacks.
*Viewstate object's value is accessible only at page level.
*This means that if a viewstate is created at MyPage.aspx,
then it may be used only within MyPage.aspx after the
postback, and cannot be used by any other page.
