This is a data column which is part of a data table and
can be used to retrieve data on row values, hierarchies and properties.
The data column implements the IDataColumn which is to
be used for non-modification operations on the data column. This class
has no public constructors, see the DataColumnCollection
class for methods which create data columns.

[SerializableAttribute] [PersistenceVersionAttribute(24, 0)] public sealed class DataColumn : DocumentNode, IDataColumn, INamable, ISearchablePropertyContainer, IDataPropertyContainer, IDataPropertiesAccessor, IRowValueProvider, IDependentComponent
The DataColumn type exposes the following members.
Methods
Name | Description | |
---|---|---|
AsT | Gets a representation of the DataColumn
for modification of properties that are not part of a standard
DataColumn. If this is a calculated column then
the CalculatedColumn class can be retrieved from
this method. If this is a tags column then the
TagsColumn class can be retrieved and if this is
a hierarchy column then the HierarchyColumn
class can be retrieved. If this is a result column then the
ResultColumn class can be retrieved. The classes
which can be retrieved will be extended in the future.
| |
CreateEventRelay(PropertyName, StatelessDependencyDeclarer) |
Creates an event relay. An event relay is a property in the document model
which propagates event.
An event is raised for the event relay whenever when the trigger returned by the
specified dependencyDeclarer fires.
(Inherited from DocumentNode.) | |
CreateEventRelay(PropertyName, StatelessDependencyDeclarer, EventRelayMode) |
Creates an event relay. An event relay is a property in the document model
which propagates event.
An event is raised for the event relay whenever when the trigger returned by the
specified dependencyDeclarer fires.
(Inherited from DocumentNode.) | |
CreatePropertyT(PropertyName, UndoableListT) |
Creates an UndoableListT and assigns it to the specified field.
The UndoableListT will have the specified propertyName.

Creates an UndoableSetT and assigns it to the specified field.
The UndoableSetT will have the specified propertyName.
(Inherited from DocumentNode.) | |
CreatePropertyTNode(PropertyName, UndoableCrossReferencePropertyTNode, TNode) |
Creates an UndoableCrossReferencePropertyT and assigns it to the specified field.
The UndoableCrossReferencePropertyT will have the specified propertyName and initialValue.
(Inherited from DocumentNode.) | |
CreatePropertyT(PropertyName, UndoablePropertyT, T) |

(Inherited from DocumentNode.) | |
CreateRuntimeConstantT |
Creates a runtime constant. A runtime constant is a property in the document model
whose value is computed once when first accessed. The value is then disposed
along with the DocumentNode.
(Inherited from DocumentNode.) | |
CreateRuntimePropertyT(PropertyName, RuntimePropertyT, DependencyDeclarer, PropertyComputerT) | Obsolete.
Creates a RuntimePropertyT.
