I'm wondering if there is any way to export a dxTreeList to Excel File? Something similar to the export configuration for dxDatagrid here: https://js.devexpress.com/Documentation/15_2/Guide/UI_Widgets/Data_Grid/Export/.
At the moment, the TreeList does not support exporting. But, we have plans to support it. However, I would not expect this feature to be implemented in the near future. Approximately, export to Excel will be implemented only in 18.2.
