CollectionSourceBase.GetEnumerable<T>(Boolean) Method

Returns a strongly typed sequence (IEnumerable<T> or IQueryable<T>) of objects from the original collection.

Namespace: DevExpress.ExpressApp

Assembly: DevExpress.ExpressApp.v26.1.dll

NuGet Package: DevExpress.ExpressApp

Declaration

C#

public IEnumerable<T> GetEnumerable<T>(
    bool wrapNotifications = true
)

VB.NET

Public Function GetEnumerable(Of T)(
    wrapNotifications As Boolean = True
) As IEnumerable(Of T)

Optional Parameters

Name	Type	Default	Description
wrapNotifications	Boolean	True	true if the returned sequence should implement the INotifyCollectionChanged interface; otherwise, false. The method considers this parameter only if the original collection implements the IBindingList interface.

Type Parameters

Name	Description
T	The type of objects in the sequence. The type parameter should match the ObjectTypeInfo.Type property value.

Returns

Type	Description
IEnumerable<T>	The strongly typed sequence of objects from the original collection. null if the original collection does not implement the IEnumerable interface.

Remarks

The GetEnumerable method returns null when the original collection does not implement the IEnumerable interface. For example, the underlying data source does not implement this interface when a List View uses Server, ServerView, InstantFeedback, or InstantFeedbackView data access mode.

To access the data in Server and ServerView modes, you can use the Collection property to get the list of objects:

var list = (ListView.CollectionSource.Collection as System.ComponentModel.IListSource).GetList();
for (int i = 0; i < list.Count; i++) {
    object obj = list[i];
}
