        AddHandler CommandButton1.Click, AddressOf commandButton1_Click
        AddHandler CommandButton2.Click, AddressOf commandButton2_Click
        AddHandler CommandButton2.SubClick, AddressOf commandButton2_SubClick
        AddHandler CommandLink1.Click, AddressOf commandLink1_Click

    Private Sub commandButton1_Click(ByVal sender As Object, ByVal e As EventArgs)
        MessageBox.Show("CommandButton1 clicked")
    End Sub


    Private Sub commandButton2_Click(ByVal sender As Object, ByVal e As EventArgs)
        MessageBox.Show("CommandButton2 main button clicked")
    End Sub


    Private Sub commandButton2_SubClick(ByVal sender As Object, ByVal e As EventArgs)
        MessageBox.Show("CommandButton2 sub button clicked")
    End Sub


    Private Sub commandLink1_Click(ByVal sender As Object, ByVal e As EventArgs)
        MessageBox.Show("CommandLink1 clicked")
    End Sub

End Class

Remarks

The Click event passes an EventArgs instance to its event handler, so it only indicates that a click has occurred. If the CommandItem is a CommandButton which has a sub button, then the Click event is raised when the main button is clicked. Clicking on the sub button raises the SubClick event.

Pressing the enter key or space bar when the CommandItem has focus is the same as clicking on the CommandItem. Pressing the enter key or space bar while holding down the control key is the same as clicking on the sub button of the CommandItem.

Requirements

Platforms: Windows 98, Windows NT 4.0, Windows Millennium Edition, Windows 2000, Windows XP Home Edition, Windows XP Professional, Windows Server 2003 family
