The following example demonstrates how to obtain underlying data corresponding to a particular visual element using the DashboardViewer's API.
In this example, the DashboardViewer.DashboardItemDoubleClick event is handled to obtain underlying data and display this data in the grid.
In the event handler, the DashboardItemMouseHitTestEventArgs.GetUnderlyingData method is called to obtain records from the dashboard's data source.
The complete sample project WinViewer - How to obtain a dashboard item's underlying data for a clicked visual element is available in the DevExpress Examples repository.
