How can I bind to a property on the PropertyGridFieldStyle?

[Magnus]

Hi! I know how to set a custom style for the field of a property grid but I cant figure out how I am supposed to make that style bound to anything that is relative to the specific PropertyDefinition of that field.

The PropertyGridField's PropertyDefinition is the default source the style's binding. The binding path of the PropertyDefinition might be "Communication.Timeout" but I want to bind the FontWeight property to "Communication.TimeoutProperty.Mode". How can this be done?
<telerik:RadPropertyGrid
    Name="PropertyGrid"
    IsGrouped="True"
    Item="{Binding SelectedItem}"
    EditMode="Single"
    RenderMode="Flat"
    FieldStyle="{DynamicResource PropertyGridFieldStyle}"
    AutoGeneratePropertyDefinitions="False">
    <telerik:RadPropertyGrid.Resources>
        <Style x:Key="PropertyGridFieldStyle"
               TargetType="{x:Type telerik:PropertyGridField}"
               BasedOn="{StaticResource PropertyGridFieldStyle}">
                    <Setter Property="FontWeight" Value="{Binding Path=???}"/>
        </Style>
    </telerik:RadPropertyGrid.Resources>
</telerik:RadPropertyGrid>

Hi Magnus,

I am afraid, that it would not be possible to achieve such binding, as the DataContext of the PropertyGridField is the PropertyDefinition, which does not have such property defined. A possible resolution would be to use a RelativeSource in the TextWeight binding and bind it to an element, as per your requirements.
