BI Dashboard for ASP.NET Core - How to add custom interactivity to a dashboard

The Web Dashboard allows you to add a custom interactivity to dashboards. For this, handle the ViewerApiExtensionOptions.onItemVisualInteractivity event. You can get data axes used to apply custom interactivity actions, specify the selection mode for dashboard item elements and so on. Use event arguments to process the multidimensional data to get the slice, axes, or tuples.

After a user changes the selection in the dashboard item, the ViewerApiExtensionOptions.onItemSelectionChanged event is raised.

This example shows the following interactivity customization:

• Select categories in the Grid dashboard item to visualize the total sales in the dxBarGauge widget. Note that the hidden 'Quantity' measure is used to pass values to the client.

  

• The Chart dashboard item highlights bars corresponding to a hovered argument value.
