The following example demonstrates how to obtain underlying data corresponding to a particular visual element using the ASPxClientDashboardViewer's API.
In this example, the ASPxClientDashboardViewer.ItemClick event is handled to obtain underlying data and invoke the dxPopup widget with the child dxDataGrid.
In the event handler, the RequestUnderlyingData method is called to obtain records from the dashboard's data source. The dxDataGrid is used to display these records.
