How to bind to a ViewModel Property from Application.Resources?

I would like to bind to a Property ShowHat which is within a ViewModel called "HatViewModel" from Application.Resources.

I can obtain access to the ViewModel via a namespace like so:

xmlns:vm="clr-namespace:HatApp.ViewModels
<Application.Resources>
<vm:HatViewModel x:Key="HatVM"/>
</Application.Resources>

But when I try to use the ViewModel's Property in a binding, it does not work.

<ControlTemplate.Triggers>
   <DataTrigger Binding="{Binding HatVM.ShowHat}" Value="True">
        <Setter Property="IsEnabled" Value="False"/>
    </DataTrigger>
</ControlTemplate.Triggers>

Any help is greatly appreciated.

You should use Source when you trying to bind a property from a static resource:

<DataTrigger Binding="{Binding ShowHat, Source={StaticResource HatVM}}" Value="True">
