'Declaration Public Property DrillDownButtonEnabled As Infragistics.Win.DefaultableBoolean
public Infragistics.Win.DefaultableBoolean DrillDownButtonEnabled {get; set;}
When DrillDownButtonEnabled is set to Default, the enabled state of the drilldown button will be determined by the Enabled property of the tool and the tool type. For a simple RadialMenuTool, the Enabled property will have no effect on the drilldown button and the user will be allowed to drill down regardless of the Enabled state. For a RadialMenuColorWellTool, drilling down and selecting a child color could affect the parent tool's color, so the Enabled property on the tool will affect the drilldown button.
Setting DrillDownButtonEnabled to True or False will enable or disable the drilldown button of the tool, irrespective of the Enabled property.
