BarItem.Command Property

Gets or sets the command to invoke when the bar item is clicked. This is a dependency property.

Namespace: DevExpress.Xpf.Bars

Assembly: DevExpress.Xpf.Core.v24.2.dll

NuGet Package: DevExpress.Wpf.Core

Declaration

C#

[Bindable(true)]
public ICommand Command { get; set; }

VB.NET

<Bindable(True)>
Public Property Command As ICommand

Property Value

Type	Description
ICommand	The command to invoke when the bar item is clicked.

Remarks

When invoking the bar item’s functionality, the command is executed first. Then, the BarItem.ItemClick and BarManager.ItemClick events fire.

Use the BarItem.BeforeCommandExecute property to perform actions immediately after an end-user has clicked the button before the Command is executed.

Example

This example shows how to specify a command and custom short cut for a bar item. A command and short cut are assigned to the item via the Command and KeyGesture properties, respectively. In the example, a bar is docked to the BarContainerControl which is created manually.

Window1.xaml

<dxb:BarManager.Items>                
    <dxb:BarButtonItem Name="btnCut" 
                       Command="ApplicationCommands.Cut" 
                       KeyGesture="CTRL+1" 
                       CommandTarget="{Binding ElementName=textBox}" 
                       Content="{Binding Command.Text, RelativeSource={RelativeSource Self}}"/>
