DxAccordion.LoadChildItemsOnDemand Property

Specifies whether the Accordion’s child items are loaded on demand.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v23.2.dll

NuGet Package: DevExpress.Blazor

Declaration

[DefaultValue(false)]
[Parameter]
public bool LoadChildItemsOnDemand { get; set; }

Property Value

Type	Default	Description
Boolean	false	true to load child items on demand; otherwise, false.

Remarks

If you set the LoadChildItemsOnDemand property to true, the Accordion loads an item’s children when the item is expanded for the first time. This mode improves the Accordion’s performance if the bound data structure contains a large number of items.

You can load child items on demand in either bound or unbound mode. Note that bound mode works with hierarchical structures only and requires the HasChildren property. The component uses this property to determine how to render items before they are expanded for the first time (for example, whether expand buttons should appear).

Razor

<DxAccordion Data="@Data" LoadChildItemsOnDemand="true">
    <DataMappings>
        <DxAccordionDataMapping Text="Name"
                                Key="Id"
                                ParentKey="CategoryId"/>
    </DataMappings>
</DxAccordion>

Note

You cannot operate with unloaded items in code (for instance, get item information).
