DataControlBase.ItemsSource Property

Gets or sets the grid’s data source. This is a dependency property.

Namespace: DevExpress.Xpf.Grid

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

NuGet Package: DevExpress.Wpf.Grid.Core

Declaration

C#

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

VB.NET

<Bindable(True)>
Public Property ItemsSource As Object

Property Value

Type	Description
Object	A data source from which the grid retrieves its data.

Remarks

The grid cannot operate without a data source. It can be bound to data from a database, from an XML file, or to any data created at runtime. The grid can be bound to any object that implements the IEnumerable interface or its descendant (e.g. IList, ICollection). To bind a grid, you should assign a data source to the ItemsSource property. Note that the grid cannot be bound at design-time - only at runtime.
