BI Dashboard for ASP.NET Core - How to save a dashboard state to cookies

The example shows how to save the current dashboard state (such as master filter or parameter values) to cookies on the client side and restore this state on the server side.

Client

The DashboardControlOptions.onDashboardStateChanged event occurs every time the dashboard state changes. In the event handler, the DashboardControl.getDashboardState method call gets the current dashboard state. The document.cookie property is used to save the dashboard state to cookies every time the state changes.

Server

The DashboardConfigurator.SetDashboardStateService method specifies a service that allows you to manage a dashboard state. In this service, the HttpRequest.Cookies property gets a collection of cookies sent by the client.
