You can enable shadows by setting Diagram.ShadowsStyle. If you need to hide them for some nodes, set the nodes' ShadowOffset to 0.

I hope that helps,
Stoyan

You will have to show and hide the shadow from respectively the NodeSelected and NodeDeselected event handlers, similarly to what you did for selection highlight earlier.

I hope that helps,
Stoyan

Use the ZOrder shadow style if the diagram contains some large background node - otherwise it will hide the shadows of nodes that are in front of it.

If that's a ShapeNode, you will have to set Transparent=false to show the shadow.

Typecast e.Node to ShapeNode to access that property:

ShapeNode shape = (ShapeNode)e.Node;
shape.Transparent = ...

Hi,

You can find attached to this post the Telephony sample from the FlowChart.NET release, with minor adjustments that show how to enable shadows on ShapeNodes on selection. It uses the settings you've provided above. It's working fine on my system (with FlowChart.NET 5.3.3).

Code
Select All
private void diagram_NodeSelected(object sender, NodeEventArgs e)
{
  ShapeNode node = e.Node as ShapeNode;
  if (node != null)
  {
    node.Transparent = false;
    node.ShadowColor = Color.Gold;
    node.ShadowOffsetX = 5;
    node.ShadowOffsetY = 5;
  }
}
