Freepornlivesex - Wpf binding not updating ui
As of writing, all properties except for the Text property, is updated as soon as the property changes (Property Changed), while the Text property is updated when focus on the destination element is lost (Lost Focus).Default is, obviously, the default value of the Update Source Trigger.
In the previous article we saw how changes in a Text Box was not immediately sent back to the source.
