Cinch V1 article links are as follows: Cinch V2 is a VS2010 solution which supports WPF/Silverlight 4, and was aimed at doing MVVM in a View 1st using design time service which would provide design time data to Blend.It uses Managed Extensibility framework to do all this.With your current implementation of Truly Observable Collection, to handle the property changed events of your collection, register something to the event that says the entire collection has been reset, anytime a property changes.

So far in this tutorial, we have mostly created bindings between UI elements and existing classes, but in real life applications, you will obviously be binding to your own data objects.

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.

The problem is that none of the buttons seems to work. The first step is to get the UI to respond to changes in the list source (Items Source), like when we add or delete a user.

What we need is a list that notifies any destinations of changes to its content, and fortunately, WPF provides a type of list that will do just that.

My target shows how different it is for a normal Windows Forms application and an XAML application. After XAML our control becomes more powerful, simple and flexible.

The Datatemplate displays a collection of data, the preceding was a simple Combobox example of a datatemplate.

How to handle them may vary, depending on what you're doing and what you're looking to accomplish, but WPF comes with two very easy solutions that you can use: The Observable Collection and the INotify Property Changed interface.

Cinch has 2 active releases Cinch is not meant for creating modular UIs, like PRISM, but it does offer a great many other features that are comparable with PRISM such as PRISM Event Aggregator == Cinch Mediator PRISM UI Service location == Cinch UI Services And to some extent PRISM Regions == Cinch Workspaces, though I have to say PRISM regions are excellent, however with Cinch V2 you can also use PRISM v4 (which is MEF based) regions/modules with ease. Cinch V1 is a VS2008 solution which only supported WPF, and was aimed at doing MVVM in a View Model 1st approach here is a diagram that may help to cement the list above: And here is a screen shot of it the demo app that went with Cinch V1 Where it used Entity Framework to use with a simple search type UI, and it demonstrates validation/editing of object, cancelling edits, messaging using the Mediator Cinch originally started as a codeproject atricle, and people asked me to move the code to codeplex, which I did, but all the documentation is available on codeproject and that should be used as main source of information regarding Cinch.
