	EnumerableRowCollection<T>^ source
)

Parameters

source
Type: System.Data::EnumerableRowCollection<T>^

The source LINQ to DataSet query from which the LINQ-enabled DataView is created.

Return Value

Type: System.Data::DataView^

A LINQ-enabled DataView object.

Type Parameters

T

The type of objects in the source sequence, typically DataRow.

DataView enables data binding scenarios for LINQ to DataSet and can be created from a LINQ to DataSet query. The DataView represents the query itself, and is not a view on top of the query. The newly created DataView infers the filtering and sorting information from the query it is created from. The DataView is then bound to a UI control, such as a DataGrid or a DataGridView, providing a simple data-binding model.

The parameter T of the input parameter source can only be of type DataRow or a type derived from DataRow.

The following query operators, only, are supported in a query used to create DataView:
