The MasterFilterSet event occurs 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 selected elements in the master filter item. To determine the selected range in the Range Filter dashboard item, use the MasterFilterSetEventArgs.SelectedRange property.
Note
The MasterFilterSetEventArgs.SelectedValues property returns the DashboardSpecialValues.NullValue or DashboardSpecialValues.OthersValue values instead of null or “Others” values, respectively.
Tip
To reduce the application load time and decrease memory consumption, handle the MasterFilterDefaultValues event that occurs before the data is loaded.
