| UnboundColumnType | Bound | A UnboundColumnType value that specifies the column’s data type and binding mode. |
Available values:
| Name | Description |
|---|---|
| Object | Indicates that the column contains values of any type. |
| Integer | Indicates that the column contains integer (16, 32, 64), Byte, SByte, or UInt (16, 32, 64) values. |
| Decimal | Indicates that the column contains decimal values (the Decimal type). |
| DateTime | Indicates that the column contains date-time values (the DateTime type). |
| String | Indicates that the column contains string values (the String type). |

| Bound | Indicates that the column is bound to a field in the control’s underlying data source. The type of data this column contains is determined by the bound field. |
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).
