  • 6 min to read

This example demonstrates how to customize a data store schema for a dashboard data source that uses a connection to the Northwind database.

To see the result, add a new query or edit the existing query.

<script type="text/javascript">
    function onBeforeRender(sender) {
        var control = sender.getDashboardControl();
        control.registerExtension(new DevExpress.Dashboard.DashboardPanelExtension(control));
@Html.DevExpress().Dashboard(settings => {
    settings.Name = "Dashboard";
    settings.Width = Unit.Percentage(100);
    settings.Height = Unit.Percentage(100);
    settings.ClientSideEvents.BeforeRender = "onBeforeRender";
