public sealed class DataView : DataTable

The DataView type exposes the following members.

Methods

  NameDescription
Public methodAddColumns
Adds columns from the columns retrieved from the dataSource using the settings in the settings parameter. Use CreateFileDataSource(String) to create a data source from a file path.
(Inherited from DataTable.)
Public methodAddRows
Adds rows from the columns retrieved from the dataSource using the settings in the settings parameter. Use CreateFileDataSource(String) to create a data source from a file path.
(Inherited from DataTable.)
Public methodBeginRefresh Obsolete.
Begins a refresh of this table, making it up-to-date with the current settings. Depending on the table type, data will be reloaded from the data source or recalculated.
(Inherited from DataTable.)
Protected methodCreateEventRelay(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.)
Protected methodCreateEventRelay(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.)
Protected methodCreatePropertyT(PropertyName, UndoableListT) (Inherited from DocumentNode.)
Protected methodCreatePropertyT(PropertyName, UndoableSetT) (Inherited from DocumentNode.)
Protected methodCreatePropertyTNode(PropertyName, UndoableCrossReferencePropertyTNode, TNode) (Inherited from DocumentNode.)
Protected methodCreatePropertyT(PropertyName, UndoablePropertyT, T) (Inherited from DocumentNode.)
Protected methodCreatePropertyTKey, TValue(PropertyName, UndoableDictionaryTKey, TValue) (Inherited from DocumentNode.)
Protected methodCreatePropertyTKey, TNode(PropertyName, PropertyName, UndoableKeyedCollectionTKey, TNode) (Inherited from DocumentNode.)
Protected methodCreateReadOnlyPropertyT
Creates a read-only property of type T and assigns it to the specified field.
(Inherited from DocumentNode.)
Protected methodCreateRuntimeConstantT
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.)
Protected methodCreateRuntimePropertyT(PropertyName, RuntimePropertyT, DependencyDeclarer, PropertyComputerT) Obsolete. (Inherited from DocumentNode.)
Protected methodCreateRuntimePropertyT(PropertyName, RuntimePropertyT, StatelessDependencyDeclarer, StatelessPropertyComputerT) (Inherited from DocumentNode.)
Protected methodDeclareInternalEventHandlers
Override this method to declare handlers of internal events.
(Inherited from DocumentNode.)
Protected methodDeserializePropertyT(SerializationInfo, StreamingContext, PropertyName, UndoableCrossReferencePropertyT) (Inherited from DocumentNode.)
Protected methodDeserializePropertyT(SerializationInfo, StreamingContext, PropertyName, UndoableListT) (Inherited from DocumentNode.)

Protected methodDeserializeReadOnlyPropertyT
Deserializes a read-only property of type T stored in info with key propertyName.
(Inherited from DocumentNode.)
Protected methodDuplicateSubtreeT
Returns a copy of the sub tree spanned from this node that has the same outwards non-owning references. The returned copy will be in state New and is intended to be attached to the document immediately.
(Inherited from DocumentNode.)
Public methodEndRefresh Obsolete.
Waits until the currently executing refresh operation is finished.
(Inherited from DataTable.)
Public methodExportDataToLibrary
Export the data in the data table as a data file in the library.
(Inherited from DataTable.)
Protected methodFinalize
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object.)
Public methodGetDistinctRows
Gets the distinct rows for the specified cursors. Note that this method is not supported for external data tables.
(Inherited from DataTable.)
Public methodGetMethods
Gets the methods that can be used in expressions on this table.
(Inherited from DataTable.)
Protected methodGetPersistedTypeName
Can be used in the deserialization constructor to get the type name that the class corresponding to this class had when it was originally serialized. Will return null if the specified caller type has no correspondence in the serialized information
(Inherited from DocumentNode.)
Protected methodGetPersistedVersion
Can be used in the deserialization constructor to get the persistence version that this class was marked with when it was originally serialized. Will return null if the specified caller type has no correspondence in the serialized information
(Inherited from DocumentNode.)
Public methodCode exampleGetRows(DataValueCursor)
Enumerates all rows for the columns specified by the given valueCursors.
(Inherited from DataTable.)
Public methodCode exampleGetRows(IEnumerableInt32, DataValueCursor)
Enumerates a subset of the rows for the columns specified by the given
valueCursors
s.
(Inherited from DataTable.)
Protected methodGetService
Override this method to provide services accessible from this node and its descendants. If you can not provide the requested service, you should call base.GetService which relays the request to the owner or to the AnalysisApplication if no owner is set.
(Inherited from Node.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Protected methodInternalTransaction
Starts an internal transaction on the document model by executing the specified executor delegate.
(Inherited from DocumentNode.)
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Protected methodOnConfigure
Allows a node to configure itself to the surrounding document.
(Inherited from DocumentNode.)
Protected methodOnConfigured
Allows a node to configure itself to the surrounding document.
(Inherited from DocumentNode.)
Protected methodOnReconfigure
