Xafari Arms

Hello!
I use the code below to intercept an action in the DevExpress browser. Can I do something similar using the Xafari browser?
How would it be?

Thank you,
Denir.

Public Class NavigatorColtrol

Inherits WindowController

Public Sub New()
MyBase.New
TargetWindowType = WindowType.Main
End Sub

Protected Overrides Sub OnActivated()
MyBase.OnActivated()

Dim showNavigationItemController As ShowNavigationItemController = Frame.GetController(Of ShowNavigationItemController)()
AddHandler showNavigationItemController.CustomShowNavigationItem, AddressOf showNavigationItemController_CustomShowNavigationItem

End Sub
