| ICommand |
The command to invoke when the bar item is clicked.
|
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.
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.
<dxb:BarManager.Items>
<dxb:BarButtonItem Name="btnCut"
Command="ApplicationCommands.Cut"
KeyGesture="CTRL+1"
CommandTarget="{Binding ElementName=textBox}"
Content="{Binding Command.Text, RelativeSource={RelativeSource Self}}"/>
</dxb:BarManager.Items>
