DataControlBase.ItemsSource Property
Gets or sets the grid’s data source. This is a dependency property.
Namespace: DevExpress.Xpf.Grid
Assembly: DevExpress.Xpf.Grid.v21.2.Core.dll
NuGet Package: DevExpress.Wpf.Grid.Core
Declaration
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.
Tip

Note
The GridControl.DataSource property is obsolete.
Example
This example demonstrates how to read data from an XML file and display it using the GridControl. If required, the changes made can be saved back to an XML file by clicking the button displayed below the grid.
