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

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