What does IsPostBack mean?

Determines whether the page has been opened from another page or by one of
its own controls in the form of a submit back to itself.

 

[bruce barker \(sqlwork.com\)]

it really means the page request included the form data item "__ViewState"
and the value of the field is valid. this is usually inferred then to be the
result of a form submit, and the server code knows the browser is sending
form values back.
