Remarks
The AutoQueryPreload method allows you to optimize Data Source Wizard schema loading.
To enable schema loading on demand or on tree node expansion in the Specify Data Source Settings page, call the AutoQueryPreload method in the BeforePrint event handler attached to the target component:
DevExpress.Analytics.Wizard.AutoQueryPreload(false);
Note
The Search function only works for data objects that have already been loaded.
