Question

Let’s say I have a WPF application which makes use of the MVVM pattern. The application’s main window defines its data context in the XAML:

<Window.DataContext>
  <vm:MainWindowViewModel/>
</Window.DataContext>

Is it possible to get a reference to the current instance of MainWindowViewModel in the XAML code-behind after InitializeComponent()? I know this is not recommended when using MVVM but I can’t figure out any other way for solving my problem.

Answer 1

sure:

var viewModel=DataContext as MainWindowViewModel;

Just cast your DataContext to the type of your viewmodel.
