Accessing Properties in other ViewModels in MVVM Light

Question

I have a main ViewModel containing a List of items which I\'m using in a certain amount of UserControls, which are displayed in a ContentCont

Answer 1

If all you need is to bind a property from the main viewmodel, while inside the content control, just use this syntax:

   ... Binding="{DataContext.mainvmpropertyname, ElementName=xxxx}"

where xxxx is the Name attached to the content control (or any control that has the main viewmodel as its DataContext). Alternatively, you can use relative binding instead of element name.
