Event Data

The DrillUpPerformed event's data class is DrillActionEventArgs. The following properties provide information specific to this event:

Property	Description
DashboardItemName	Gets the name of the dashboard item.
DrillDownLevel	Gets the drill-down level.
Values	Gets values from the current drill-down hierarchy.

The event data class exposes the following methods:

Method	Description
IsNullValue(Object)	Returns whether the specified value is DashboardSpecialValues.NullValue.
IsOthersValue(Object)	Returns whether the specified value is DashboardSpecialValues.OthersValue.

Remarks

The DashboardControl.DrillUpPerformed event is raised when end-users drill down into the specified dashboard item’s element. When an end-user returns to the previous detail level (drill up), the DrillUpPerformed event is raised.
