Use Commands with RadRibbonView Buttons

All RadRibbonView buttons provide a standard ICommandSource implementation. This is why you can bind the RadRibbonButtons to commands that will get executed when a button is clicked. For this purpose you can use the following properties.

  • Command - gets the command that will be executed when the command source is invoked.

  • CommandParameter - represents a user defined data value that can be passed to the command when it is executed.

  • CommandTarget - the object on which the command is being executed.

As all butons implement the ICommandSource interface, you can use them with any command that implements the ICommand interface, for example the DelegateCommands.

Here is an example of a command usage in a MVVM scenario. The command is located in the ButtonViewModel class.

public class ButtonViewModel
    public ButtonViewModel()
        this.MyCommand = new DelegateCommand(p => Execute(p), p => CanExecute(p));

    public DelegateCommand MyCommand { get; set; }

    private bool CanExecute(object p)
        if (p != null)
            return true;
            return false;

    private void Execute(object p)
        MessageBox.Show("Executed: \n" + p.ToString());
Public Class ButtonViewModel
    Public Sub New()
        Me.MyCommand = New DelegateCommand(Function(p) Execute(p), Function(p) CanExecute(p))
    End Sub

    Public Property MyCommand() As DelegateCommand
            Return m_MyCommand
        End Get
        Set(value As DelegateCommand)
            m_MyCommand = Value
        End Set
    End Property
    Private m_MyCommand As DelegateCommand

    Private Function CanExecute(p As Object) As Boolean
        If p IsNot Nothing Then
            Return True
            Return False
        End If
    End Function

    Private Sub Execute(p As Object)
        MessageBox.Show("Executed: " & vbLf + p.ToString())
    End Sub
End Class

Set the ButtonViewModel as the DataContext of your UserControl.

public Example()
    this.DataContext = new ButtonViewModel();
Public Sub New()
    Me.DataContext = New ButtonViewModel()
End Sub

In the XAML provide the bindings for the command and set the command parameter.

This can be applied to each of the RadRibbonButtons. To learn more about them read here. Commands can be used with any control, placed in the RadRibbonView, that implements the ICommandSource interface.

<telerik:RadRibbonView x:Name="xRibbonView">
    <telerik:RadRibbonTab Header="Home">
        <telerik:RadRibbonGroup Header="Home Group">
            <telerik:RadRibbonButton Width="Auto"
                                     Command="{Binding MyCommand}"
                                     Content="Execute Command" />
