Wpf combobox itemssource binding not updating
In this pattern, all the controls on your form are data bound to properties on your “View Model” class.
While there are lots of examples of how to do this with Text boxes, List boxes, and even master-detail views, it seems that examples for binding Combo boxes are a little thin on the ground.
I would be interested to hear in the comments if you think either approach has benefits over the other.
One consideration is that Silverlight doesn’t seem to support Collection View at the moment.

The default is Default, which returns the default Update Source Trigger value of the target dependency property.
However, the default value for most dependency properties is Property Changed, while the Text property has a default value of Lost Focus.
A programmatic way to determine the default Update Source Trigger value of a dependency property is to get the property metadata of the property using Get Metadata(Type) and then check the value of the Default Update Source Trigger property.
Bindings that are Two Way or One Way To Source listen for changes in the target property and propagate them back to the source. Usually, these updates happen whenever the target property changes.How wpf combobox works is it will listen to collection change event of the observable collection, and updates the UI.
