Bind DependencyProperty to Visibility in a Style

There is a boolean DependencyProperty in a control, named IsRunning, which indicates that the control is doing something. I want to create a Style with Visibility of this control set to Visible if IsRunning == true, or Collapsed if IsRunning == false.

The control can be used in a page like this:

<TheControl Style="{StaticResource MyStyle}" IsRunning="{Binding CategoryListLoaded}"/>

and the style I tried (I too have tried TemplatedParent instead of Self without luck):

<Style x:Key="MyStyle" TargetType="TheControl" >
    <Setter Property="Visibility" Value="{Binding RelativeSource={RelativeSource Self}, Path=IsRunning, Converter={StaticResource BoolToVisibilityConverter}}"/>
</Style>

With the above code i get a XamlParseException. I don't want to set the visibility in the page, I want to control the visibility with the style, because I have many of these controls and only one style.

doing in Style binding is still not supported I think... but there is a good old article that has a helper as a solution!

Since IsRunning is a bool, have you tried adding visibility straight to the control

<TheControl Style="{StaticResource MyStyle}" IsRunning="{Binding CategoryListLoaded}" Visibility="{Binding CategoryListLoaded, Converter={StaticResource BoolToVisibilityConverter}}"/>
