Allows you to provide data for the DashboardObjectDataSource.
The DataLoading event is raised when the dashboard needs to load data from a data source of the DashboardObjectDataSource type. Use the e.Data property to provide data for this data source. This object should implement the IEnumerable or IListSource interface. Use the e.Parameters property to obtain dashboard parameters required to modify your data query.
Tip
You can subscribe to this event and subsequently load a dashboard bound to an object data source. The event fires and enables you to supply data to the loaded dashboard.
For other data source types (for instance, DashboardSqlDataSource or DashboardOlapDataSource), you can handle the Dashboard.ConfigureDataConnection event to customize connection parameters.
