Wpf listview not updating Tante2 phone sex show webcam

The other options are Property Changed, Lost Focus and Explicit.

The first two has already been described, while the last one simply means that the update has to be pushed manually through to occur, using a call to Update Source on the Binding.

If you want the full control, you can use the Explicit value and then do the updates manually, but this does take a bit of the fun out of working with data bindings.

This is just as easy, but once you start doing it, you might discover something that disappoints you: Changes are not automatically reflected, like they were in previous examples.

As you will learn in this article, you need just a bit of extra work for this to happen, but fortunately, WPF makes this pretty easy.

This is the price you will have to pay if you want to bind to your own classes and have the changes reflected in the UI immediately.

Obviously you only have to call Notify Property Changed in the setter's of the properties that you bind to - the rest can remain the way they are.

To see how all of these options work, I have updated the example from the previous chapter to show you all of them: As you can see, each of the three textboxes now uses a different Update Source Trigger.
