aspx_professional thread: Help! Control Execution Lifecycle
Message #1 by "Lynn Curtner" <lynn.curtner@p...> on Mon, 22 Apr 2002 15:32:39

I'm struggling to understand the "Control Execution Lifecycle".
Specifically: I'm dynamically creating a TextBox <see code below> during
the page Load event, and when the user enters text into this TextBox and
submits the page back to the server, that text is persisted across the
postback. This is just the behavior that I want, but I don't understand
how it can happen, since according to the documentation of the "Control
Execution Lifecycle", the "Load View State" phase takes place before the
page Load event, at which time my TextBox is not even created! How can
this ViewState data be loaded into a control that doesn't exist? Any
insight into what's going on here would be greatly appreciated.
TIA,
Lynn Curtner
