Create a class boolean variable for the left and right button defaulted to false. When the mouse down event fires set the variable to true and check if both are true. When the mouse up fires set the variable to false.

    public bool m_right = false;
    public bool m_left = false;

    private void MainForm_MouseDown(object sender, MouseEventArgs e)
    {
        m_objGraphics.Clear(SystemColors.Control);

        if (e.Button == MouseButtons.Left)
            m_left = true;
        if (e.Button == MouseButtons.Right)
            m_right = true;

        if (m_left == false || m_right == false) return;
        //do something here
    }

    private void MainForm_MouseUp(object sender, MouseEventArgs e)
    {
        if (e.Button == MouseButtons.Left)
            m_left = false;
        if (e.Button == MouseButtons.Right)
            m_right = false;
     }
