The AsyncDataLoading event handler receives an argument of the DataLoadingEventArgs type. The following properties provide information specific to this event.

Property Description

DataSourceComponentName Get the component name of the data source for which the event has been raised.
DataSourceName Gets the name of the data source for which the event has been raised.

The AsyncDataLoading event is raised when the dashboard needs to load data from a data source assigned using the DashboardObjectDataSource. Use the event parameter's DataLoadingEventArgs.Data property to provide data for this data source. This object should implement the IEnumerable or IListSource interface.

For other data source types (for instance, DashboardSqlDataSource or DashboardOlapDataSource), you can handle the DashboardControl.ConfigureDataConnection event to customize connection parameters.
