Hi,

When this event is raised, the node has already been rendered with its current shape, and then changing the Shape property will invalidate the view and cause DrawNode to be called again.

If you need to draw a BPMN shape only as an element of a custom-drawn node, you could call Shapes.BpmnWhatever.Draw(...). This will render the shape in its default 100x100 coordinate space. You can apply translate and scale transforms to the graphics object to render the shape with a different size and position.

Another option is to use composition instead of custom drawing, e.g. you can attach additional ShapeNodes to the node and set their shapes to Bpmn.

I hope that helps,
Stoyan

Hi,

You can set ShadowBrush to null to hide the shadow.

Setting any visual property invalidates a part of the diagram and might lead to DrawNode event raised again for custom-drawn nodes. In the DrawNode handler you are supposed to call e.Graphics methods to draw custom graphics, and not change the node's properties from it.

What exactly are you trying to draw anyway?
