>Handling events can get fairly involved and inefficient. Implementing event handlers on a document that is not fully known at design time (database driven Web pages or pages with data binding, for example) is only possible with event bubbling . As a result, authors frequently implement a single global handler at the top of the event chain to update everything. On the other hand, with dynamic properties, authors can automatically determine a minimal and optimal recalculation of properties and evaluate only the expressions that really need to be evaluated.

Andrus;

Thank you for the information. This looks very interesting and I am going to look into it as it is a concept that would be very valuable to me. I will let you know what I find out.
