IAFList.IsPaging Property
This read-only property indicates whether the collection is currently paging its items.

Namespace:  OSIsoft.AF
Assembly:  OSIsoft.AFSDK (in OSIsoft.AFSDK.dll) Version: 3.1.1.1182

Syntax

bool IsPaging { get; }
ReadOnly Property IsPaging As Boolean
	Get

Dim instance As IAFList
Dim value As Boolean

value = instance.IsPaging
property bool IsPaging {
	bool get ();
}
abstract IsPaging : bool with get

Property Value

Type: Boolean
Returns if the collection is currently paging its items.

Remarks

A collection that supports paging (see SupportsPaging) will have this property set when the collection's Count is greater than the PageSize. When this occurs, the SDK will automatically page the collection so not all items are loaded into memory. A page of items is loaded when needed. An unreferenced page may be garbage collected.

For a collection that does not support paging, this property will always return .

When the collection is currently paging, the IAFListSort methods will throw an exception because the collection is too large for the sort operation.
