You can control the background settings of the diagramming surface through the following properties:

  • IsBackgroundSurfaceVisible: a boolean property that determines whether the background surface of the RadDiagram should be displayed. Its default value is true.

Set IsBackgroundSurfaceVisible

this.radDiagram1.DiagramElement.IsBackgroundSurfaceVisible = true;

Me.RadDiagram1.DiagramElement.IsBackgroundSurfaceVisible = True

IsBackgroundSurfaceVisible = true IsBackgroundSurfaceVisible = false

  • Background: this property is of type Brush and it controls the fill of the RadDiagram background.

Set Background
