Event Data
The DrillDownPerformed 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 DrillDownPerformed 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 DashboardControl.DrillUpPerformed event is raised.
The example demonstrates how to synchronize Master Filter and Drill-Down actions between different dashboards:
Note
The DrillActionEventArgs.Values property returns the DashboardSpecialValues.NullValue or DashboardSpecialValues.OthersValue values instead of null or “Others” values, respectively.
