Class EnumerablePagedSource

A page-sliced, observable collection that can be consumed by any target grid control other than , such as Microsoft.Maui.Controls.CollectionView. It exposes the current page of items and updates when SfDataPager navigates. This implementation does not extend PagedCollectionView to avoid conflicts with framework CollectionView binding, but provides all the same properties and methods that the DataPager requires for paging functionality.

Syntax

public class EnumerablePagedSource : Object, IPagedSource, INotifyCollectionChanged, INotifyPropertyChanged, IEnumerable, IEnumerable<object>

Constructors

EnumerablePagedSource(IEnumerable, Int32)

Initializes a new instance of the EnumerablePagedSource class.

Declaration

public EnumerablePagedSource(IEnumerable source, int pageSize = 0)

Parameters

Type	Name	Description
System.Collections.IEnumerable	source	The underlying source sequence.
System.Int32	pageSize	The default page size to use for the initial page slice.

Properties

Count

Gets the number of items in the current page.

Declaration

public int Count { get; }

Property Value

Type
System.Int32

CurrentPage

Declaration

public ObservableCollection<object> CurrentPage { get; }

Property Value

Type
System.Collections.ObjectModel.ObservableCollection<System.Object>

ItemCount

Gets the number of items in the current page.

Declaration

public int ItemCount { get; }

Property Value

Type
System.Int32

MaxItemsCount

Gets or sets the maximum number of items.

Declaration

public int MaxItemsCount { get; set; }

Property Value

Type
System.Int32

PageCount

Gets the total number of pages.

Declaration

public int PageCount { get; }

Property Value

Type
System.Int32

PageIndex

Gets the zero-based index of the current page.

Declaration

public int PageIndex { get; }

Property Value

Type
System.Int32

PageSize

Gets or sets the number of items per page.

Declaration

public int PageSize { get; set; }

Property Value

Type
System.Int32

UseOnDemandPaging

Gets or sets a value indicating whether on-demand paging is used.

Declaration

public bool UseOnDemandPaging { get; set; }

Property Value

Type
System.Boolean

Methods

GetEnumerator()

Returns an enumerator that iterates through the current page.

Declaration

public IEnumerator GetEnumerator()

Returns

Type	Description
System.Collections.IEnumerator	An enumerator for the current page.

LoadDynamicItems(Int32, IEnumerable)

Loads items dynamically for on-demand paging.

Declaration

public void LoadDynamicItems(int startIndex, IEnumerable items)

Parameters

Type	Name	Description
System.Int32	startIndex	The zero-based start index of the items.
System.Collections.IEnumerable	items	The items to load into the current page.

MoveToPage(Int32)

Moves to the specified page index.

Declaration

public bool MoveToPage(int pageIndex)

Parameters

Type	Name	Description
System.Int32	pageIndex	The zero-based page index to move to.

Returns

Type	Description
System.Boolean	True if the page change succeeded; otherwise, false.

Events

CollectionChanged

Occurs when the collection changes.

Declaration

PropertyChanged

Occurs when a property value changes.

Declaration
