PLinqInstantFeedbackDataSource.ListSource Property

Gets or sets the source collection. This is a dependency property.

Namespace: DevExpress.Xpf.Core.ServerMode

Assembly: DevExpress.Xpf.Core.v18.2.dll

Declaration

C#

public IListSource ListSource { get; set; }

VB.NET

Public Property ListSource As IListSource

Property Value

Type	Description
IListSource	The source collection implementing IListSource.

Remarks

To support Parallel LINQ, you should specify the source collection for a PLINQ data source and bind it to the grid. The source collection must implement IEnumerable<T>. You should not provide the exact type of its elements, because the type is automatically evaluated at runtime.

There are three ways to specify the source collection:

• Use a ItemsSourceDataSourceBase.ItemsSource if a source collection implements System.Collections.Generic.IEnumerable<T>.
• Use a PLinqInstantFeedbackDataSource.ListSource if a source collection implements System.ComponentModel.IListSource.
• You can dynamically specify the source collection within the PLinqInstantFeedbackDataSource.GetEnumerable event handler.
