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 methodAddTransformation
Adds a transformation to the table. The transformation will be applied on the source columns in the table (i.e., the columns originating from a data source or the result of an add columns or add rows operation.) Calculated columns will not be affected.
(Inherited from DataTable.)
Public methodAddTransformations
Adds a sequence of transformations to the table. The transformation will be applied on the source columns in the table (i.e., the columns originating from a data source or the result of an add columns or add rows operation.) Calculated columns will not be affected.
(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.)
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.)
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.)
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.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Public methodRefresh
Refreshes this table to be up-to-date with the current settings. This will reload data from the DataSource or recalculate depending on the type of table.
(Inherited from DataTable.)
Public methodRemoveRows
Remove rows from this table.
(Inherited from DataTable.)
Public methodReplaceData
Replace the data in the table with the columns in the data source. Use CreateFileDataSource(String) to create a data source from a file path.
(Inherited from DataTable.)
Public methodSelect
Returns the rows that matches the where clause expression. The expression must be a boolean Spotfire expression.
