Property Value

Type Default Description
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).

Boolean

Indicates that the column contains Boolean values (the Boolean 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).
