'Declaration Public ReadOnly Property Drill As DrillDownAppearance
public DrillDownAppearance Drill {get;}
This property exposes the Infragistics.UltraChart.Resources.Appearance.DrillDownAppearance to the UltraWebChart control, allowing the developer to set properties related to UltraWebChart's drill down behavior at run-time (defining drill down hierarchies in the design-time environment is unsupported.)
