The MouseButtonState enumeration specifies constants which correlate to the state of a mouse button.

The following example shows a mouse event handler that determines which buttons are currently pressed by checking the button state of each mouse button.

Private Sub MouseDownHandler(ByVal sender As Object, ByVal e As MouseEventArgs)
    If e.RightButton = MouseButtonState.Pressed Then
        MessageBox.Show("The Right Mouse Button is pressed")
    End If

    If e.LeftButton = MouseButtonState.Pressed Then
        MessageBox.Show("The Left Mouse Button is pressed")
    End If

    If e.MiddleButton = MouseButtonState.Pressed Then

        MessageBox.Show("The Middle Mouse Button is pressed")
    End If

    If e.XButton1 = MouseButtonState.Pressed Then
        MessageBox.Show("The XButton1 Mouse Button is pressed")
    End If

    If e.XButton2 = MouseButtonState.Pressed Then
        MessageBox.Show("The XButton2 Mouse Button is pressed")
    End If
End Sub
