Specifies how the TreeList export nodes that contain child nodes.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.2.dll

NuGet Package: DevExpress.Blazor

Declaration

[DefaultValue(TreeListExportRowExpandMode.KeepExpandState)]
public TreeListExportRowExpandMode RowExpandMode { get; set; }

Property Value

Type	Default	Description
TreeListExportRowExpandMode	KeepExpandState	An enumeration value.

Available values:

Name	Description
None	All nodes are exported as a plain list (in the first outline).
KeepExpandState	If nodes are expanded when exported from the TreeList source, they remain expanded in the new document.
ExpandAll	All nodes are expanded.
CollapseAll	All nodes are collapsed.

Remarks

The TreeList preserves row expansion state during export. Use the RowExpandMode property to expand or collapse all rows in the exported document, or to export all rows as a plain list.

The following example expands all nodes:

async Task ExportXlsx_Click() {
    await MyTreeList.ExportToXlsxAsync("ExportResult", new TreeListXlExportOptions() {
        RowExpandMode = TreeListExportRowExpandMode.ExpandAll
    });
}
