WPF - InputBindings binding View to ViewModel

Hello all.

Short version:  How do I bind the InputBindings on a WPF Usercontrol to a property on the object assigned to DataContent?


Long version:  We use MVVM design but our first attempt at it so I can't say we have the pattern down pat.  We have a Provider that supplies commands to the ViewModel and the View Binds the context menu to those commands.  Works great, but now I need hot keys.  Because only the Provider knows what the commands are and what keys should be assigned to them, it needs to provide a collection of these KeyBindings.  That's easy.  What I can't figure out, is how populate the View's InputBindings collection with the items in that property.  I tried the following:


    <!--<UserControl.InputBindings Source="{Binding Path=KeyBindings}" />-->
    <!--<UserControl.InputBindings ItemsSource="{Binding Path=KeyBindings}" />-->

    <!--<InputBindingCollection Source="{Binding Path=KeyBindings}" />-->
    <!--<InputBindingCollection ItemsSource="{Binding KeyBindings}" />-->

None of these compile.

Property on DataContent (ViewModel) class:

System.Windows.Input.InputBindingCollection keyBindings = new System.Windows.Input.InputBindingCollection();
public System.Windows.Input.InputBindingCollection KeyBindings
{
get { return keyBindings; }
}
