Event Data

The QueryChildNodes event's data class is DevExpress.XtraEditors.BreadCrumbQueryChildNodesEventArgs.

Remarks

The QueryChildNodes event allows you to dynamically populate the selected node’s BreadCrumbNode.ChildNodes collection. Only nodes whose BreadCrumbNode.PopulateOnDemand property equals true raise the QueryChildNodes event. See the Breadcrumb Edit Control topic for an example.

The QueryChildNodes event fires for nodes created at both design-time and runtime.
