DataSourceWizardExtension Class

A Web Dashboard extension that is the Data Source Wizard.

Declaration

export class DataSourceWizardExtension implements ISupportOptionExtension<DataSourceWizardExtensionOptions>

Remarks

Refer to the DataSourceWizardExtensionOptions class that contains the extension’s options to configure the extension.

The Web Dashboard supports two Data Source Wizard types:

• DataSourceWizardExtension - a standard wizard.
• MultiQueryDataSourceWizardExtension - a multi-query version.

The Web Dashboard uses the DataSourceWizardExtension by default. The code snippet below shows how to enable the other wizard:

dashboardControl.unregisterExtension('dataSourceWizard');
dashboardControl.registerExtension(new DevExpress.Dashboard.MultiQueryDataSourceWizardExtension(dashboardControl));

See the following topic for information on how to use the DashboardControl’s client-side API: Extensions Overview
