Please, can you tell me what "binding" stands for?
I can only translate to a synonym of link, in french.
Bindings are a feature of a language or framework where you declare
a connection of some kind between data items, usually involving a
GUI control at one end of the connection, and the framework takes
care of updating the connected items when the other end changes.
Bindings may be either one-directional or uni-directional.
Ah, like RB allowed for years like "Enable PushButton1 when ListBox1
has a selection". Simply?
They simplify the amount of source code that has to be written
considerably, especially with complex GUI development and many
items referring to the same data model.
Some frameworks allow property bindings, eg: having a graph item
color adjusted by a slider without going through an intermediate
data model. (WPF allows this but the cut-down version in
Silverlight requires the data model.)
They were deprecated in RB several versions ago, with the last
traces being removed in 2008r2.
