Xaml - add existing control to grid

Question

Trying to develop using MVVM:

I have this Csla.PropertyStatus control that is created in my ViewModel. I want to add it in the xaml (via binding, i think) and set some additional properties there (such as the target).

I don't know how i could do that, not even if that is possible.

I was looking for something like

<csla:PropertyStatus Instance="{Binding Path=MyStatus}" 
                     Target="{Binding ElementName=txtTextBox}" 
                     Grid.Column="2" Grid.Row="0"/>

Is that possible somehow?... i NEED to create it in the ViewModel because i need to set some property that the view (XAML) is not allowed to know about.

Edit: The property i'm talking about is the model. The PropertyStatus needs a reference to the business object to perform the validation. But considering the paradigm of MVVM (or as i understand it), the view should be decoupled from the model, and should only know about the ViewModel. I might change that approach, though...

Answer 1

You CAN'T do this. BTW, the view is all about UI controls and their properties, so saying the view is not allowed to "know about" a property on one of its elements is a bit... extreme. A description of what you are trying to accomplish here might help in providing you with a decent answer.
