	Does TemplatedNode have an equivalent to ShapeNode's CustomDraw.Additional2 functionality, where I could let WpfDiagram do a full pass on drawing the TemplatedNode and then I get to add additional drawing that is not constrained by the node's bounds? (At least that's how I think CustomeDraw.Additional2 works.) Cheers, Joel.

	If you are looking for a way to render graphics outside of node.Bounds, you can achieve that by setting negative margins on some Xaml element in the template: Code <Style TargetType="{x:Type diag:TemplatedNode}"> <Setter Property="Template"> <Setter.Value> <DataTemplate DataType="{x:Type diag:TemplatedNode}"> <Grid> <Rectangle Fill="Blue" Margin="-10,-10,-10,-10" /> <Rectangle Fill="Red" /> </Grid> </DataTemplate> </Setter.Value> </Setter> </Style> If you need to run low-level rendering code via DrawingContext API, you could override UIElement.OnRender in a custom element class and add that to the node's template.
