Dashboard for Web Forms - How to obtain a dashboard item's underlying data for a clicked visual element

The following example uses the DashboardControl's client-side API to get underlying data that corresponds to a particular visual element.

In this example, the ViewerApiExtensionOptions.onItemClick event is handled to obtain underlying data and invoke the dxPopup widget with the child dxDataGrid. In the event handler, the e.requestUnderlyingData method returns records from the dashboard's data source. The dxDataGrid displays these records.
