How to: Customize Connection Settings before ASPxDashboardViewer Connects to a Database

Important

This documentation applies to v16.2. Starting with v17.1, the ASPxDashboardViewer control is in maintenance mode. In v19.1, the new Web Dashboard Control replaces the old Web Dashboard Viewer. This means that the Web Dashboard Viewer will not be included in our installation packages. See our blog post for more information.

This example demonstrates how to customize connection settings before ASPxDashboardViewer connects to a database using the ASPxDashboardViewer.ConfigureDataConnection event.

In this example, the dashboard visualizes data from the secured Microsoft Access database. To visualize data from this database file, it is necessary to provide connection parameters (a path to the database file, a user name and a password for authentication).
