DxTreeListEditor.LoadChildrenOnDemand Property

Specifies whether DxTreeList should render child nodes only when users expand their parent.

Namespace: DevExpress.ExpressApp.Blazor.Editors

Assembly: DevExpress.ExpressApp.Blazor.v25.1.dll

NuGet Package: DevExpress.ExpressApp.Blazor

Declaration

C#

public bool LoadChildrenOnDemand { get; set; }

VB.NET

Public Property LoadChildrenOnDemand As Boolean

Property Value

Type	Description
Boolean	true if you want to render the rows for child nodes on-demand; otherwise, false.

Remarks

When you use DxTreeListEditor to display a tree of ITreeNode objects, XAF renders child nodes on-demand when users expand their parent nodes for the first time. To render all node rows during control initialization, set the LoadChildrenOnDemand property to false.

using DevExpress.ExpressApp;
using DevExpress.ExpressApp.Blazor.Editors;

namespace MySolution.Blazor.Server.Controllers;

public class LoadChildrenOnDemandController : ViewController<ListView> {
    protected override void OnActivated() {
        base.OnActivated();
        if (View.Editor is DxTreeListEditor editor) { 
            editor.LoadChildrenOnDemand = false; 
        }
    }
}

This functionality has certain limitations. For more information, refer to the following topic: Blazor.DxTreeList.ChildrenLoadingOnDemand.
