||CalculatedDataColumn is a specialization of the general DataColumn class, and represents a field for which the value is not stored directly in the DataTable, but calculated at runtime. In contrast to the LookupDataColumns, which obtain their value automatically by referring to another table,
calculated fields depend on the developer to provide custom code that determines the value of the field, as needed. For this, an implementation of CalculatedDataColumn.Evaluator...
||A DataColumn represents the definition of an individual field in a DataTable. Descendant classes, such as CalculatedDataColumn and LookupDataColumn exist for more specialized field types, but a regular DataColumn represents a
real field that is...
||The DataColumnChangedEvent event is fired when a structure of the table has changed, i.e. columns were added ore removed.
||The DataColumnCollection is used to hold a set of DataColumns in the DataTable instance. Usually, it is filled with columns by a RemoteDataAdapter while initializing the data table with the Schema. But you can still add/remove columns manually, for example for adding CalculatedDataColumn or LookupDataColumn columns.
||The DataRow class represents a single data row in a DataTable. Each DataRow not only maintains its data, but also keeps track of any changes made to its values, until they have been successfully applied.
||The DataRowChangedEvent event is fired when a structure of the table has changed, i.e. columns were added or removed.
||The DataRowCollection is used to hold a set of DataRows in the DataTable instance.
||The DataTable is one of the core classes in Data Abstract for operating with tabled data. It is used to represent the client version of an individual record set, or data table, that has been retrieved from the server...
||The DataTableView represents customized view of a DataTable for sorting, filtering, grouping and navigation.
||LookupDataColumn is a specialization of the general DataColumn class, and represents a field for which the value is not stored directly in the DataTable but looked up from a secondary table via a reference source field. The source field is another...
||The PropertyCollection is used to hold a set of additional properties in the DataTable instance. Cosider is as an inheritor of a java.util.HashMap with a few additional methods. All constructors are also inherited from HashMap, thus not described here...
||The TableChangedEvent event is fired when a data or structure of the table has changed.
