Actually I ready keep the sensitive information on server only, but there comes a time when knowing when an element has changed a value could be useful. I find the reasons more compelling as I use AJAX and client side scripting. An example would be for an extender control that needs to do some action when the control that it has extended (i.e. text input) has had its value changed is used to set other internal things within the control. If there was a trigger that fired when this happened, you would not force a programmer to use your behavior to set things up when the value changed. I know that under the current paradign this is not a common occurance, but in the future it could become a greater problem in making more user friendly applications. Just my thoughts.
