Hi!, Thanks for your reply!

I found the way to address my issue,

In the buttons collection of the toolbar (ToolBarButton Collection Editor) there is a property for the button name in the Design Section, but in the class itself there is no Name property (e.g. TBtnAdd.Name, does not exists).

Then ButtonClick event I did this comparison with the button name

Private Sub TBar_ButtonClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.ToolBarButtonClickEventArgs) Handles TBar.ButtonClick

        If e.Button Is TBtnAdd Then
            OpAdd()
        ElseIf e.Button Is TBtnExplore Then
            OpExplore()
        Else
            ' Nothing
        End If

    End Sub

TBtnAdd, TBtnExplore are the names that i've assigned to the buttons in design time.
