AutoQueryPreload Function

Allows you to choose to automatically load child data items and to search by nested items in the complex nested data source.

#Declaration

TypeScript
export const AutoQueryPreload: DevExpress.Analytics.Internal.IGlobalSubscribableValue<boolean>

#Parameters

Name Type
newVal boolean

#Returns

Type
boolean

#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.
