NuGet Package: DevExpress.Wpf.NavBar
Declaration
Property Value
Type | Description |
---|---|
ICommand | An ICommand object to invoke when the NavBar item is clicked. |
Remarks
If a NavBarItem was selected via a click at runtime, a Command is executed and the NavBarItem.Select and NavBarItem.Click events fire. If an end-user clicks an already selected item, the NavBarItem.Select event is skipped.
The Command can receive additional custom parameters (specified via the NavBarItem.CommandParameter) and a target object on which the command is executed (specified via the NavBarItem.CommandTarget).
The code below illustrates an example of defining a command:
xmlns:custom="clr-namespace:myApplicationNamespace">
<Window.CommandBindings>
<CommandBinding Command="{x:Static custom:MainWindow.myCommand}"
Executed="myCommandExecuted"
CanExecute="myCommandExecute"/>
</Window.CommandBindings>
namespace myApplicationNamespace {
public partial class MainWindow : Window {
public static RoutedCommand myCommand = new RoutedCommand();
public MainWindow() {
InitializeComponent();
}
private void myCommandExecuted(object sender, ExecutedRoutedEventArgs e) {
//Actions to perform
. . .
}
private void myCommandExecute(object sender, CanExecuteRoutedEventArgs e) {
//Case of command's availability
if (. . .) {
e.CanExecute = true; }
}
}
}
To use the command as the user clicks a NavBarItem, assign it to the Command property of this group as in the following code:
<dxn:NavBarGroup Content="My Group" Name="navBarGroup1" Command="{x:Static custom:MainWindow.myCommand}" />
