BarSubItemLink Class

Represents a link to a BarSubItem object.

Assembly: DevExpress.Xpf.Core.v18.2.dll

Declaration

C#
VB.NET

public class BarSubItemLink :
    BarButtonItemLink

Public Class BarSubItemLink
    Inherits BarButtonItemLink

Remarks

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:
