Gets or sets the lookup editor’s (ComboBoxEdit, LookUpEdit) data source. This is a dependency property.

Namespace: DevExpress.Xpf.Editors

Assembly: DevExpress.Xpf.Core.v23.2.dll

NuGet Package: DevExpress.Wpf.Core

Declaration

C#

[Bindable(true)]
public object ItemsSource { get; set; }

<Bindable(True)>
Public Property ItemsSource As Object

Property Value

Type	Description
Object	An object that represents the data source from which the LookUpEdit retrieves its data.

Remarks

The LookUpEdit editor cannot operate without a data source. The editor can be bound to any object that implements the IEnumerable interface or its descendant (e.g., IList, ICollection).

When the ItemsSource property value changes, the ItemsSourceChanged event occurs.

The lookup editors support binding to data sources in Server Mode and Instant Feedback UI Mode.
