Event Data

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

Property	Description
DashboardItemName	Gets the name of the dashboard item.
SelectedRange	Gets the selected range in the Range Filter dashboard item.
SelectedValues	Gets currently selected records in the master filter item.

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 MasterFilterSet event is raised when an end-user changes the state of the master filter.

The MasterFilterSetEventArgs class exposes the MasterFilterSetEventArgs.DashboardItemName property that allows you to determine the name of the master filter item which causes the event.

Use the MasterFilterSetEventArgs.SelectedValues property to obtain values of currently selected elements in the master filter item. To determine the selected range in the Range Filter dashboard item, use the MasterFilterSetEventArgs.SelectedRange property.

The example demonstrates how to synchronize Master Filter and Drill-Down actions between different dashboards:

Note

The MasterFilterSetEventArgs.SelectedValues property returns the DashboardSpecialValues.NullValue or DashboardSpecialValues.OthersValue values instead of null or “Others” values, respectively.
