Remarks
In v21.1 and higher, the UnboundType property is hidden. Use the TreeListColumn.UnboundDataType property instead to make a column unbound and specify the column’s data type. Compared to the UnboundType property, the TreeListColumn.UnboundDataType property can accept any data type (including previously unavailable TimeSpan and DateTimeOffset).
