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.

Remarks

The TreeList preserves row expanded 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:

csharp

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