This tutorial shows how to add the DashboardExtractDataSource to an in-memory data source storage, and make it available to users.

1. In your application, add the SalesOverview.dat file to the App_Data folder from the C:\Users\Public\Documents\DevExpress Demos 25.2\Components\Data directory.

2. In the dashboard configuration file (for example, DashboardConfig.cs / DashboardConfig.vb), create a public method that returns the configured dashboard’s data source storage (DataSourceInMemoryStorage) and define the Extract Data Source.

3. Call the DashboardConfigurator.SetDataSourceStorage method to configure the data source storage. Use the created CreateDataSourceStorage method as the SetDataSourceStorage parameter and handle the DashboardConfigurator.ConfigureDataConnection event to pass the connection parameters to the Extract Data Source.

Users can bind dashboard items to data in the Web Dashboard’s UI.
