Pass parameters from WPF user control to Windows Form User Control via WindowsFormsHost

Hi, how can I pass a WPF User Control values (dependency objects) to a called Windows Form UserControl?

<WindowsFormsHost><local:WinFormUserControl     ></local:WinFormUserControl></WindowsFormsHost>

Let's say I want to bind dependency property 'Wa' of WPF user control to an object inside WinFormUserControl.

How should the receiving object be defined in the WinForm UserControl and how to pass the values?

Thanks,
