How can I apply FillStyle.Color property to grouped nodes?

There is no direct way to fill the interior of grouped nodes with the required color. However, you can try the following workaround. In the attached sample first, I have ungrouped all the grouped nodes by using UnGroup() method of WinForms Diagram Controller. Then, I iterated through the Nodes collection and set the FillStyle.Color for each node. Finally, I grouped all the nodes by using the Group() method. You can use the FillPath.FillStyle.Color to fill the interior of a node with the required color.

C#

FilledPath fillpath;
this.diagram1.Controller.UnGroup();
foreach (Node node in this.diagram1.Model.Nodes)
{
fillpath = (FilledPath)(((node is FilledPath) ? node : null));
fillpath.FillStyle.Color = Color.Green;
}
this.diagram1.Controller.Group();
 

VB

Dim fillpath As FilledPath
Me.diagram1.Controller.UnGroup()
For Each node As Node In Me.diagram1.Model.Nodes
If (TypeOf node Is FilledPath) Then
fillpath = CType((node), FilledPath)
Else
fillpath = CType((Nothing), FilledPath)
End If
fillpath.FillStyle.Color = System.Drawing.Color.Blue
Next node
Me.diagram1.Controller.Group()
