Important

To learn how to use the DashboardConfigurator‘s API, see the Server-Side API Overview topic.

To prepare the ASPxDashboard/MVCxDashboard for first use, you need to create the dashboard and data sources storages.

Use the static DashboardConfigurator.SetDashboardStorage method to create a storage that will contain dashboards. You can use predefined dashboard storages (DashboardFileStorage or DashboardInMemoryStorage) or you can implement the IDashboardStorage interface to provide your own logic for managing dashboards.
Note
The DashboardConfigurator uses the DashboardInMemoryStorage if you do not create the dashboard storage.
Prepare data sources that will be used to supply dashboards with data. You can do this in two ways.
- Add the required connections string to the application configuration file. These connection strings can be used later in the Web Dashboard’s UI to create new data sources.
- Use the static DashboardConfigurator.SetDataSourceStorage method to create a storage that contains data sources available to end-users. You can use a predefined implementation of the in-memory storage (DataSourceInMemoryStorage) or you can implement the IDataSourceStorage interface to provide a custom data source storage.

The DashboardConfigurator class also exposes an API used to supply the dashboard with data at runtime (for instance, using the DashboardConfigurator.ConfigureDataConnection or DashboardConfigurator.DataLoading events).

The following example shows how to set up ASPxDashboard with the DashboardConfigurator settings.

Set the UseDashboardConfigurator property to true and use the DashboardConfigurator to process data-related operations and handle data-related events (set the dashboard /data source storage, specify a connection provider, etc).
