Occurs when the editor needs to navigate to a dynamically populated node for the first time.

Namespace: DevExpress.XtraEditors.Repository

Assembly: DevExpress.XtraEditors.v24.1.dll

NuGet Package: DevExpress.Win.Navigation

Declaration

C#

[DXCategory("Events")]
public event BreadCrumbQueryChildNodesEventHandler QueryChildNodes

VB.NET

<DXCategory("Events")>
Public Event QueryChildNodes As BreadCrumbQueryChildNodesEventHandler

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.
