Examples

The following example demonstrates how to bind a dashboard to a List object.

The quantity values are provided at runtime. The dashboard data source is added to the Dashboard.DataSources collection on the first load.

Click the Reload Data button to call the DashboardViewer.ReloadData method. It raises the DashboardViewer.DataLoading event and supplies the dashboard with updated data.
