Hello, My name is Jesús from Spain, I'm a .NET developer and I just discovered this great web few days ago. I have some questions about MVVM pattern and I will be glad if you can answer they.

Do you have a process for testing the data template's appearance WITHOUT spinning up your app just to test how the data looks?

I'm starting to dip my toe into WPF, and I would like to have the collections in my application work with as an ItemSource. I tried implementing INotifyCollectionChanged. I'm ok with that except that then I have to reference WindowsBase.dll in about 15 dll's. Is there another interface that WPF can use for binding that I might already...
I am debugging an algorithm that is being represented by a set of ViewModels. In order to debug this algorithm I would like to redraw the View while stepping through part of the algorithm. Is this possible? (I would prefer to just repaint, not do what they call "DoEvents" to process all events.) ...
It appears that the ValueChanged and SourceUpdated events will fire simply by setting the DataContext. Does anyone know of a way to tell whether the value changed is actually from some user interaction? A simple example is to have a "Save" button on a WPF form that is disabled until the user actually changes the data. Since both Value...

How can I retrieve the item that is selected in a WPF-treeview? I want to do this in XAML, because I want to bind it. You might think that it is SelectedItem but apparently that does not exist is readonly and therefore unusable.

This question is similar to another one I asked, but whereas in that case I wanted to know about forcing a binding to update from XAML or a view model, in this case I'd like to know about wrapping this up into a custom WPF FrameworkElement. The functionality I'm after is a span of text that indicates how long ago something happened. <T...
