There are also a number of performance improvements that we can make when data binding in our applications. The simplest of which can be obtained by simply setting the
Binding.Mode property correctly. In order to make data binding possible, the Framework attaches handlers to listen out for changes to our data bound properties.
For two-way bindings, event handlers will be attached to the
PropertyChanged event of the
INotifyPropertyChanged interface to listen to changes in our data model objects or View Models and to various other
XxxChanged events in the relevant binding target controls to listen to UI-based property changes.
When we only require one way bindings, we can save some computing resources by setting the
Mode property of the
Binding class to the appropriate member of the
BindingMode enumeration. If you remember, when a data bound property is for display purposes only, we should set its
Mode property to
OneWay and when we have no need to update an editable field from...
