Wpf binding not updating property

In the previous article we saw how changes in a Text Box was not immediately sent back to the source.Instead, the source was updated only after focus was lost on the Text Box.For those situations where you need more control of the process, this property will definitely help though.Just make sure that you don't update the source value more often than you actually need to.This behavior is controlled by a property on the binding called Update Source Trigger.It defaults to the value "Default", which basically means that the source is updated based on the property that you bind to.For that reason, I have added a button next to the Text Box, which will update the source value on demand.

The first one is set to Explicit, which basically means that the source won't be updated unless you manually do it.

OK, so the title is a little ambitious, but there is nothing wrong with setting yourself lofty aims!

Because of the depth of this topic I have decided to split this tutorial up into a series of blog posts, each of which explore a different aspect of the binding framework.

In the examples in Stylet master repository, you have a Master-Detail example which is working, and the model does not implement INPC So you give a Product Group (not a VM) to a new Product Group View Model.

The Product Group View Model mutates the Product Group, and you expect the Product Groups View Model to show the changes to that Product Group?
