ChunkList(Int32, Boolean) Constructor

Initializes a new instance of the ChunkList<T> class.

Namespace: DevExpress.Xpf.ChunkList

Assembly: DevExpress.Xpf.Core.v24.1.dll

NuGet Package: DevExpress.Wpf.Core

Declaration

C#

public ChunkList(
    int capacity,
    bool useChunksCache = false
)

VB.NET

Public Sub New(
    capacity As Integer,
    useChunksCache As Boolean = False
)

Parameters

Name	Type	Description
capacity	Int32	The approximate number of items in the data source.

Optional Parameters

Name	Type	Default	Description
useChunksCache	Boolean	False	true, to store chunk indexes for collection items in a special hash table; otherwise, false.

Remarks

The chunk size is calculated based on the value of the capacity parameter:

C#

int chunkSize = Math.Sqrt(capacity);

If the useChunksCache parameter is set to true, the ChunkList<T> instance will store chunk indexes for collection items in a special hash table. The hash table will take up additional memory, but chunk indexes for items will be retrieved almost instantly.
