MVVM: IUIVisualizer and event management with behaviors
the ViewModel class. The type must be a WPF Window-derived type (i.e. done a little differently if you’ve not done much WPF work.
WPF allows us to customize the visuals however we like, so here the
panel class and then injecting my behavior into the element where the attached property

some some of the concepts we’ve talked about already through a new sample – a simple picture

WPF MVVM Helper Library (WPF + MVVM = testability)
usage around the WPF and Silverlight technology stack. When teaching WPF, I
always always introduce students to MVVM as part of the Essential WPF class, it's an incredibly
useful utility classes, helpers, wrappers, etc. There's been a lot of talk about the Model-View-ViewModel pattern recently and it's
usage useful pattern that really separates the UI from the code behind behavior.

Part 2: Changing WPF focus in code

WPF Data Providers
One of the nifty new features of the WPF platform is the pluggable data providers.
Both of these derive from the abstract class System.Data.DataSourceProvider which
of the UI until the data is fully available.
Another interesting thing about this class is that we can define
It ships with two out of the box:
ObjectDataProvider: allows you to execute binding expressions
against an object and it's methods
XmlDataProvider: loads an XML data source and makes it available

(Possibly) better validations in WPF
I've never cared much for the built-in validation mechanisms provided by WPF.
I just don't think any of them feel natural to the way we build WPF applications today.
Basically, there are essentially three mechanisms built into WPF for validations:
Validation Rules
Exceptions
IDataErrorInfo
Validation rules are checked prior to transferring the value from the bound control
to your source (typically the business object).

Using Model – View – ViewModel with Silverlight
have found it extremely easy to use when developing very different applications and have used the design pattern recently in both ASP.NET, WPF and Silverlight applications. However easy as it might be is seems to confuse people as I have seen some terrible examples where people make a complete mess of things. Josh Smith did an excellent screen cast for Pixel8 on using MVVM with WPF, you can find it here . Even thought the UI technology used doesn't change the basic MVVM pattern there are some subtle differences, like not easily being able to use ICommand in Silverlight,
