A DataView is a derived view which values are derived from
a DataTable. It cannot be added to the
DataTableCollection. A DataView cannot be
serialized to the document.

[SerializableAttribute] [NotPersistedAttribute] public sealed class DataView : DataTable
The DataView type exposes the following members.
Methods
| Name | Description | |
|---|---|---|
 | AddColumns | 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.) |
| AddRows | 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.) |
| BeginRefresh | 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.) |
 | 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.) |
