BarManager.Items Property

Provides access to the collection of bar items owned by the BarManager.

Namespace: DevExpress.Xpf.Bars

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

NuGet Package: DevExpress.Wpf.Core

Declaration

C#

public BarItemCollection Items { get; }

VB.NET

Public ReadOnly Property Items As BarItemCollection

Property Value

Type	Description
BarItemCollection	A BarItemCollection object that specifies the collection of bar items owned by the BarManager.

Remarks

To display a bar item within a bar or menu, it must be added to the Items collection. Then, a link to this bar item must be added to the target bar, sub-menu or popup menu via their ItemLinks collection.

See Items and Links to learn more.

Example

This example shows how to create three bars (File, Edit and StatusBar) using the BarManager component. Actions for bar elements are defined by commands implemented in the MyViewModel class.   The window’s DataContext is set to a MyViewModel class descendant, which is automatically generated by the DevExpress.Mvvm.POCO.ViewModelSource object. This descendant automatically generates commands for all public methods in the MyViewModel class (the OpenFileCommand, NewFileCommand and SetAlignmentCommand are generated).

The result is shown below:

Example

This example shows how to embed in-place editors into a bar using BarEditItem objects. Two editors (DateEdit and SpinEdit) are added with the BarEditItem.EditSettings property. Values for the editors are provided using the BarEditItem.EditValue property.
