Add custom UIControl to any Editor

Hi Friends,

Some of my properties have there "IsReadOnly" state controled by another "bool" property, and I want to control the "bool" state by pressing a button.

I want this button to be displayed inside the editor, to the right (eg. with a "PadLock" image).

What I wish is to add this button as :

- an adorner to the actual editor UI control, whatever the editor is

- a classic button added to the right of the actual editor UI control, for example within a dockpanel containing both.

To achieve case #1, I need to have somehow access to the underlying UI control created for a given editor, and then add my adorner.

But I don't know how and were to access the actual UI control after its creation and before its display ...

To achieve case #2, I've created a custom Editor whos ValueTemplate looks like :

<DockPanel
	LastChildFill='True'
>
	<Button
		DockPanel.Dock='Right'
		Margin='1'
		Focusable='False'
		Style='{StaticResource {x:Static themes:SharedResourceKeys.EmbeddedButtonBaseOverrideStyleKey}}'
	/>
	<ContentControl
		Content='{Binding}'
		ContentTemplate='{Binding " + $"{nameof(MyPropertyModel.LockedOriginalEditor)}.{nameof(PropertyEditor.ValueTemplate)}" + @"}'
	/>
</DockPanel>

MyPropertyModel.LockedOriginalEditor is the original Editor, for example a DoublePropertyEditor.

Display is OK, but when ProperyGrid tries to bind to the underlying editor, it expects a DoublePropertyEditor but finds my custom "high level" editor instead, and many bindings fail.

Would appreciate some help on that one ;-)
