How can I test if BarItem has click event associated with it and if doesn't disable the item

All I really need to know is How do I test BarButtonItem1 has a Itemclick event assigned.

Michael,
As I said above, there is no easy way to implement this functionality. .Net doesn't provide this feature directly for any control. Currently, I am investigating this opportunity and provide you an answer as soon as possible.
Thanks,

Hello,
You can check whether a BarButtonItem is subscribed to the ItemClick using the following code:

Visual Basic
Private Sub simpleButton1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles simpleButton1.Click  
    Dim itemClickInfo As FieldInfo = GetType(BarItem).GetField("itemClick", BindingFlags.Static Or BindingFlags.NonPublic)  
    Dim eventsInfo As FieldInfo = GetType(Component).GetField("events", BindingFlags.Instance Or BindingFlags.NonPublic)  
    Dim itemClick As Object = itemClickInfo.GetValue(barButtonItem1)  
    Dim Events As EventHandlerList = TryCast(eventsInfo.GetValue(barButtonItem1), EventHandlerList)  
    If Not Events Is Nothing Then  
        Dim handler As ItemClickEventHandler = TryCast(Events(itemClick), ItemClickEventHandler)  
        If Not handler Is Nothing Then  
            MessageBox.Show("The barButtonItem1 object is subscribed to the ItemClick event!")  
        End If  
    End If  
End Sub  

Thanks,
